Conceptualising online fashion brand recognition: scale development and validation

Purpose – This study aims to develop and validate a scale for measuring online fashion brand recognition (OFBR). Design/methodology/approach – Given the existing literature on brand, multiple stages of studies were conducted as a part of the scale development process. The OFBR scale was validated by a step-by-step process following the scale validation methodology suggested in the specialised literature. Findings – The results demonstrate the 25 items of five unique factors that form the OFBR construct and confirm the strong validity of the construct. This finding suggests that the five-dimensional approach (online brand familiarity, online visual simplicity, online aesthetic attraction, online brand emotion and online social reputation) plays important role to form OFBR. Practical implications – A valid and reliable OFBR scale provides a foundation for broadening the understanding on the important constructs that form OFBR, which is essential for online fashion retailing. Knowledge of the crucial antecedents that influence consumers towards online fashion products can enhance marketers’ capability to position their brands towards their target markets. Originality/value – The relevance of this study lies in validating the scale for measuring OFBR for the first time in the literature on online fashion brand.


Introduction
Fashion is an activity that reflects and exposes an individual's appearance using clothing, apparel and accessories. Conceptualising fashion is composed of thoughtful and behavioural processes through which consumers present their lifestyle status to their respective society (Vieira, 2009). Fashion items are identified as a highly expressive product category that communicates the associated recognised brand preference (O'Cass, 2004). Research on fashion clothing brand has attracted considerable attention in the field of fashion marketing and literature on brand management (O'Cass and Siahtiri, 2014). Evidence suggests that consumers are comfortable with roaming in an online environment to check and purchase trendy fashion brand products (Van Deursen and Van Dijk, 2014). In recent times, the volume of clothes, footwear and other fashion-related products sold via the internet has rapidly grown as a whole worldwide (Israeli and Avery, 2017). Retailers need to adopt a different approach to remain competitive in the online market using online brand recognition (BR) tools amongst targeted online consumers. Thus, marketers should demonstrate increased intensity in fashion BR in an online environment to improve their brand identity and further attract online consumers. Recently, academicians and experts have stimulated tangible and intangible brand elements to form and extend previous theories of BR. Furthermore, they have also tested and extended various models and validated scales across industry contexts related to brand (Iglesias et al., 2019), online retail brand (Bhattacharya and Anand, 2019), fashion items (Ladhari et al., 2019;Cheung et al., 2019) and branding of fashion products (Lopez and Fan, 2009). Previous research defined online brand as "a brand that has an online presence". According to , online branding pertains to how online channels are used to support brands, which in essence are the sum of the characteristics of a product, service or organisation as perceived and experienced by a user, consumers or other stakeholders.
As explained by Keller (1993), consumers should recognise brand names when the components of a brand are visible and reflect the brand's symbolic expression through advertising. Therefore, BR by a large pool of consumers implies that the particular brand is reputable and familiar (Grewal et al., 2004;Bilgihan, 2016). The target consumers should recognise a brand to save time by reducing search costs. This notion is increasingly SJME 24,1 important in providing continuity and securing consumer commitment in a fast-moving online fashion brand marketplace (Hajli et al., 2017). Thus, the qualities and benefits of products must be refined and transformed in a competitive manner to communicate over an online medium and form BR in the mind of consumers, which is increasingly critical for online retail fashion brand stores (Keller et al., 2011). Selecting a prominent brand name to form recognition in the mind of consumers should be given priority as consumers purchase fashion brand products from online stores. Thus, forming an effective scale for online fashion BR (OFBR) is a strategic issue for online fashion retailers; the current study extensively contributes to this end.
Therefore, further understanding is necessary to identify the types of constructs that evoke BR in the context of online fashion retailing that can develop favourable online BR in the minds of consumers. Hence, the challenges associated with measurement are closely linked to theoretical constraints. The current study identifies two main research gaps, namely, the lack of conceptual clarity and need for a reliable and valid measurement scale to assess BR in the context of online fashion retailing. This study emphasised on formative protocol while validating scale as strongly suggested in Grace et al. (2020). First, the researchers build upon existing studies to conceptualise OFBR as a multidimensional construct (Hossain et al., 2020). Second, on the basis of this conceptualisation, we develop a formative model, given that the direction of causality is derived from items for each construct that forms OFBR (Grace et al., 2020). Third, we provide empirical testing and examine the relationship between the proposed construct of OFBR and consumers' behavioural intention (BI) in purchasing fashion products from online stores .
The remainder of the article is structured as follows. We provide a critical review of the existing research on BR in the context of online fashion products to conceptualise constructs that are theoretically related to OFBR (i.e. antecedents and consequences). Afterwards, the study showcases a series of scale validation procedures by adopting recommendations from Churchill (1979) and Rossiter (2002). This scale development will facilitate the understanding of future research in terms of how OFBR evokes marketing efforts towards online fashion retailing to influence the behaviour of target consumers. Finally, we discuss the theoretical and managerial importance of the validated OFBR scale and give directions for future research.
2. Literature review BR determines whether a brand will be embedded in consumers' consideration for current or next purchase (Chakravarti and Janiszewski, 2003). In general, consumers purchase products that they recognise at the time of purchase decision-making (Chan et al., 2016). Previous studies have focused on enhancing BR using mixed methods of traditional marketing (e.g. advertising and price promotion). However, future research should assess BR from various contexts, such as online environment (Huang and Sarigöllü, 2014). To date, scholars have measured BR using a single-item scale (Matthes et al., 2007) and also measured the brand awareness (Aaker, 1996). The present study conceptualises online BR from the context of brand names of fashion products using the five dimensions adapted from the study De Marchis et al. (2018), namely, online brand familiarity (OBF), online visual simplicity (OVS), online aesthetic attraction (OAA), online brand emotion (OBE) and online social reputation (OSR). De Marchis et al. (2018) examined cued recall (pertained to in this study as recognition) and perception towards commercial logos. In this study, we used the term cued recall with respect to the psychological aspect of the consumer under the scope of online BR.

Online fashion brand recognition
Consumers' decision-making for products is highly driven by the associated BR, which refers to whether consumers recognise a brand through exposure (Huang and Sarigöllü, 2014). Although brand awareness and BR have been interchangeably used in previous studies, BR with brand recall is two pivotal dimensions that illustrate brand awareness (Keller, 1993). Brand awareness pertains to the consumers' ability to recognise and recall a brand under various circumstances. Increased brand awareness drives towards achieving loyalty and long-term customer relationship opportunities for brands with consumers (Khan et al., 2015). This aspect of brand awareness consists of BR and brand recall (Aaker, 1996). Leveraging on BR and brand recall measures can be used to assess brand awareness (Walsh et al., 2008). BR is denoted as aided awareness, that is, an aided technique that enables consumers to simply remember a brand when a cue is presented (Aaker, 1992). Conversely, brand recall is defined as spontaneous awareness or the ability of consumers to retrieve a brand without mention of any product class or brand names (Aaker, 1996). Brand awareness represents a continuum of brand knowledge that ranges from the initiation of recognition of a brand name to a cognitive formation of such brand. A subtle difference is observed between brand awareness and BR (Melis et al., 2016;Rajavi et al., 2019). Similarly, BR is distinct from brand recall in terms of differences in the definitions of aided and spontaneous awareness. Therefore, measuring BR saliently and comprehensively is necessary considering its distinct difference from brand awareness and brand recall. BR is a fundamental driving force for the purchase decision-making of consumers. A prominent brand name that consumers recognise and experience will receive priority as consumers form purchase decisions. Active brand name formation is the focal point of establishing BR (Klink, 2003;Klink and Athaide, 2012). The conventional approach of measuring BR is giving consumers a set of choices with brand names and asking them to cite the brand names that they recognise. Despite the distinctiveness and ubiquitous application of BR, little attention has been given to understand the relevant and comprehensive dimensional approaches to measure BR. Thus, the present study aims to develop a multidimensional scale for measuring OFBR.

Conceptualising the dimensions of online fashion brand recognition
We adapted the five-dimensional approach in the conceptualisation of OFBR for three reasons. Firstly, we aim to develop the scale for BR because multidimensional scaling is one of the well-accepted and popular tools for solving a wide range of marketing problems (Bijmolt and Wedel, 1999). Particularly, BR using a multidimensional approach remains largely unexplored. Secondly, the five dimensions are conceptually consistent with BR in the context of the present study, as justified in the previous discussion. Finally, to the best of our knowledge, no research has adapted the five dimensions for understanding the role of BR in the context of brand names of online fashion products. Thus, we intend to further extend the validation of the five dimensions in a new context.
Brand familiarity is denoted as the required amount of time that consumers spend on processing information about a brand (Bapat, 2017), which is less for familiar brands compared with unfamiliar brands . Brand familiarity enables consumers to engage in message or information processing within a short period (Martin and Strong, 2016). In addition, brand familiarity retains knowledge about a brand in the consumers' memory where BR spontaneously occurs (Verhellen et al., 2016). Consumers' brand experience is also defined through brand familiarity, which consumers achieve by prior experience and exposure from the brand (Eisend and Stokburger-Sauer, 2013). In the context of the online environment, consumers want to purchase their desired products from dotcom sites because they recognise the brands through shopping experience (Rahman and SJME 24,1 Mannan, 2018). Several researchers have explored brand familiarity in the context of traditional retail stores and investigated its influence on shoppers' purchase intention (Park and Stoel, 2005;Ali et al., 2018). Particularly, in an online context, consumers search for Web information of familiar brands in compare to unfamiliar brands (Iglesias et al., 2011;. In other words, well-known online brands may have an advantage from being better favoured than less familiar online brands (Ha and Perks, 2005;Park and Lennon, 2009). However, brand familiarity construct has yet to be explored in the context of the online environment and linked with online BR; the current study addresses these concerns to contribute to the marketing literature (Nepomuceno et al., 2014).
On another note, visual complexity refers to the extents of elements included in an object followed by the detailed information portrayed by that object (Deng and Poole, 2010). Visual complexity affects consumer's perception and BIs in a wide range of contexts in both online and offline contexts (Kusumasondjaja and Tjiptono, 2019). Visual complexity is associated with brand logo, which portrays the visual recognition of a brand. Despite the generic negative effect of visual complexity on consumers' processing and purchase behaviours (Khachatryan et al., 2018), consumers' BR is high when the exposure level is also high for visually complex abstracts, such as logos Das, 2016a, 2016b). Therefore, BR can be enhanced through high exposure to the visual complexity of a branded logo design. Hence, BR is important in a competitive online market. In online marketplaces, sellers highlight information about their products and services directly within pictures of the products for advertising purposes. Such application enhances the visual complexity of the image and provides further information in such a manner that supports buyers' purchase judgement. However, when other sellers adopt the same strategy, the given image of products or services through an online platform will be less striking to gain recognition from the target customers. Thus, we suggest that online retailers should reduce buyers' effort by simplifying the representation of the brand and placing the product image conspicuously in the online platform to provide other viable means for catching buyers' attention and recognition towards the brand (Lee et al., 2018).
Merriam-Webster (1993) defined: [. . .] aesthetics as the branch of philosophy dealing with such concept as the beautiful, the ugly, the inspiring, the comic, etc., as applicable to the fine arts, with a view to establishing the meaning and validity of critical judgments concerning works of art, and the principles underlying or justifying such judgments.
Aesthetic attraction has received significant attention from academic researchers and practitioners. A consumer evaluate the functional value of a product and consider experiential value, such as products' aesthetic attraction (Creusen et al., 2018). The appearance of a product along with perceived beauty is referred to as the aesthetic dimension of product design (Homburg et al., 2015). Aesthetic attraction plays a pivotal role when consumers do not have prior knowledge of the brand (Honea and Horsky, 2012). In an online context, web aesthetics positively expose opportunities for marketers to understand consumers behaviour and formulate strategy accordingly (Tractinsky and Lowengart, 2007). The aesthetic appeals of a product considerably enhance BR and thus stimulate the consumers' linking with the brand and brand value (Choi et al., 2016). The aesthetic attraction of the product captures consumers' attention and enhances brand appeal and recognition (Mugge et al., 2018;Crolic et al., 2019). Therefore, online BR is portrayed through the aesthetic attraction of the fashion products. In this study, researchers denote emotionality as a brand emotion that refers to the emotional bonding between the brand and consumers. Brand emotion emerges from emotional branding, which is a consumer-centric, relational and story-driven approach, built through the consumers' senses and emotions (Junaid et al., 2019). Emotional experiences with a brand induce a positive effect on subsequent evaluation and reaction towards the brand (Langner et al., 2016). A positive experience creates positive emotions and satisfaction, which in turn leads to the consumers' emotional attachment to preferred brands (Grace et al., 2020). Therefore, emotion is also a crucial dimension of the brand and BR (Homburg et al., 2015). Bowden (2009) revealed that brand engagement activities, such as BR and advocacy, are outcomes of emotions or emotional involvement of a particular brand and customer. Moreover, brand emotion evokes the senses of consumers, which increases brand awareness and recognition (Kim et al., 2003). In fact, knowledge of brand emotion from the perspective of online retailing is still in its infancy (Bagdare and Jain, 2013). Previous scholars have agreed that emotion has a strong connection to online BR-related behaviours (Marken, 2003).
The social reputation of a brand refers to the overall quality as seen and judged by consumers (Dowling, 2016). Consumers seek attention through brand consumption to gain accepted in social environments and maintain social relationships (Bian and Forsythe, 2012). Consumers tend to use socially reputed and recognised brands to portray an image of prestige in social environments, which enhances consumers' self-esteem (Bhattacharya and Sen, 2003). In the context of the technology development of fashion brands through online retail platforms, sellers largely benefit by attracting consumers to interact with brands. The positive reputation of a brand can spread through social media and form the reputation of the retail stores surrounding the consumers' environment, which builds friendly attention and even affection towards brands and stimulates customers' BR for particular fashion products (Nash, 2019;Dahana et al., 2019). Therefore, BR can be explained through the social reputation of a brand.
To determine the formative or reflective construct, we carefully evaluated four rules of Jarvis et al. (2003), and according to Jarvis et al. (2003) Type II model, we have formed OFBR (formative) through five factors (i.e. OBF, OVS, OAA, OBE and OSR), (Figure 1); these five factors are reflecting by 25 items (see the section "Generating scale items").

Scale development and assessment measures
We adopted the recommendations from Churchill (1979) and Rossiter (2002) as steps for the formative measure of scale development and validation procedure of OFBR ( Figure 2). We combined both processes due to their individual limitations (Diamantopoulos, 2005). The researchers skimmed and scanned the relevant literature, followed by an exploratory research method, such as focus group discussion (FGD). The exploratory research was conducted on only one group that comprises three BBA, three MBA and two EMBA students to earn partial credit in undergraduate-and graduate-level marketing management courses. The FGD included eight participants comprised of 50 per cent male and 50 per cent female, with an average age of 23.65 years. The moderators for the FGD were the researchers and a graduate research assistant with marketing research experience. The moderators provided a brief summary of BR, brand, online environment in the context of fashion brands and OFBR-related constructs. After carefully examining the FGD, the moderators manually recorded the transcripts to initially develop the items of the OFBR scale. Along with the focus group, researchers also adopted a small-scale experience survey (ES) in the form of in-depth interviews with 25 individuals (i.e. ten online consumers, five online fashion retailers, five researchers and five academic experts). The participants were selected through the researchers' requirement for eligibility in term of providing sufficient ideas and insight about online fashion brands and fashion BR. The current study adopted SJME 24,1  Steps of scale development and assessment for OFBR Step 1 Specify the domain of OFBR construct Average and other statistics, summarizing distribution score Step 2 Generate Sample of items Step 8: Scale application Step 3: Collect Data Step 4: Refinement and Purify the measures of OFBR Step 5: Data Collection Step 6: Assess Reliability Step 7 Source: Adapted from Churchill (1979) and Rossiter (2002) Online fashion brand recognition such process to generate a substantial number of items under the measured constructs that may represent consumers' OFBR. The moderator used the same technique in the FGD as a discussion guide and procedure for conducting one-to-one interviews with the interviewees. As the researchers explored a considerable amount of overlap amongst the perception of the interviewees regarding OFBR (compared with the focus group), these interviews also yielded additional items that the current study incorporated to the OFBR scale. During the FGD and ES, the researchers displayed several retail outlets of online fashion products (e.g. Ajkerdeal.com, Daraz.com.bd, Bagdoom.com, PriyoShop.com, Othoba.com, Branoo.com, Shoparu.com, ShoppersBD.com, Clickbd.com and Shadmart.com), which were screened and presented through smartphones and tablets to create the stimuli and represent various types of OFBR appeal.
The researchers extended and examined the outcome of the first steps by content validity to reduce the number of items under each construct. A survey questionnaire was then administered to assess dimensionality, validity and reliability. The researchers applied exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) to refine and reduce the items. In addition, EFA and CFA were also used to confirm whether the number of dimensions conceptualised can empirically verify the study object (i.e. OFBR). CFA was conducted using analysis of moment structures (AMOS 20).

Domain definition
To form a composite of indicators, a sound theoretical framework is required, which should clearly define the phenomenon to be measured and its subcomponents. Thus, on the basis of the above literature review, the study defines "OFBR" as cues for recalling a fashion brand in an online environment, where consumers recognise a brand because of the presence of the cues from spontaneous awareness about the online fashion brand. According to Rossiter (2002), the construction of the definition comprises a concrete object (i.e. online fashion brand) with elicited attributes (items).

Generating scale items
The current study explores the relevant constructs of OFBR through a critical examination of the relevant literature, where previous researchers adopted the reliability and validity of the measurement in a different context. Hence, the literature search helped us in identifying how variables (e.g. OBF, OVS, OAA, OBE and OSR) have been previously defined, and the appropriateness of selecting these dimensions has been justified. In addition, the researchers conducted the FGD (eight members) and ES with 25 participants to generate items that could offer important ideas and insights into the relevant constructs of OFBR, as derived from the extensive literature search. Researchers have identified the formation of OFBR as OBF (three items), OVS (three items), OAA (three items), OBE (three items) and OSR (two items), for a total of 14 items adapted from previous research. After an initial addition, another 20 items (OBF (three items), OVS (five items), OAA (four items), OBE (four items) and OSR (four items)) were generated from the outcomes of the FGD and ES methods. Therefore, a total of 34 items were initially generated. After checking and deleting double barrel, items that are redundant and ambiguous and with a total correlation of less than 0.50 were eliminated. Finally, a pool of 25 items was retained for further analysis (Table I).

SJME
24,1 men and women who have purchased or intend to purchase fashion products from online fashion retail stores. The researchers applied the convenience sampling method, which was operationalised in two major metropolitan areas, namely, Dhaka and Chittagong, via the mall intercept method. In Bangladesh, major online retail stores are operating in these two cities, and consumers living in these cities tend to be conscious of purchasing online fashion brands and of their purchasing power. The respondents were limited to consumers who purchased any fashion brand items from online within the previous six months because this study is focused on fashion products only. Data were collected from survey questionnaires from October 2018 to January 2019. Amongst the 300 survey questionnaires distributed, 230 were finally analysed after excluding questionnaires with missing responses. The survey instrument comprised of 25 items, and the researchers verified the reliability and validity of the measures of the OFBR constructs. In total, 60 per cent of the participants were female, and 40 per cent were male. Amongst them, 60 per cent were working, 20 per cent were housewives and 20 per cent students. As a whole, the majority of the respondents have bought online apparel products (40 per cent), whereas 60 per cent bought other categories of fashion products (e.g. bags, wristwatches, bracelets, stylish home and living materials and footwear). Afterwards, the subjects indicated how much they perceived OFBR, which was listed using the 25 items on a five-point Likert scale that ranged from 1 = strongly disagree to 5 = strongly agree. Note:s *Marked items were deleted later for having item-to-total correlations lesser than 0.50. The italic items generated from both FGD and ES outcomes. The bold items generated from ES and FGD separately Table I.

To avoid the common method variance of the measurement constructs, the researchers applied procedural and statistical tests for control common method bias (variance). The researchers define common method variance as that which is attributable to the measurement rather than to the construct of interest. Variance can influence the results due to response biases, such as halo effects, social desirability, acquiescence, leniency effects or yes and no answers (Spector, 1994;Podsakoff et al., 2003).
Therefore, the study collected data through face-to-face surveys and a question randomisation option for each respondent in a shuffled approach. In addition, the researchers carefully constructed the items to avoid ambiguous or unfamiliar terms and vague concepts; when such concepts were used, the respondents were provided with examples; the questions were presented in a simple, specific and concise manner, double-barrelled questions and complicated syntax were avoided (Tourangeau et al., 2000). In terms of the statistical measure to control for common method variance, the researchers tested Harman's single-factor test with an unrotated factor solution through EFA using SPSS. The result indicates an explained variance of 23.6 per cent, which is relatively less than the threshold of 50 per cent as suggested by Podsakoff et al. (2003). The current research adopted the structural equation modelling (SEM) approach using AMOS because this method can provide the best solution for multidimensionality with regard to scale development (Farooq, 2016). In addition, SEM can be useful for measuring the psychometric properties of a scale or construct (Babin and Svensson (2012). The researchers also used Harman's single-factor test through CFA using AMOS for further analysis. The method bias was not substantial because the hypothesised model poorly fits the data within a single-factor model (goodness-of-fit index (GFI) = 0.70; adjusted GFI (AGFI) = 0.67; normed fit index (NFI) = 0.65; IFI = 0.69; Tucker-Lewis index (TLI) = 0.66; root mean square residual (RMR) = 0.10; root mean squared error of approximation (RMSEA) = 0.13). In summary, the findings confirm the nonexistence of common method variance in the data set (Malhotra et al., 2006).

Item refinement and purification
This step is essential for improving the scale because it identifies the ineffective items under each construct to avoid confusion. The researchers applied the item-to-total correlation matrix test for the items and verified the Cronbach's a values of each construct. At this stage, a total of 230 filled questionnaires were administered. The questionnaire contained 25 OFBR items, which were rated using a Likert scale that ranges from 1 (strongly disagree) to 5 (strongly agree). Each respondent was requested to fill the survey questionnaire regarding their preferred online fashion product brand. Table II presents the results in relation to the item-to-total correlation values for each construct and corresponding coefficient a values. In addition, the findings indicate that the item-to-total correlation values for all items reached more than 0.70. Items with item-to-total correlation values of <0.50 were omitted. All Cronbach's a values were above 0.70, which indicated strong internal consistency of the data. Therefore, the research retained 25 items for further analyses (Table II).

Exploring the dimensional structure of online fashion brand recognition
After refining and purifying the scale items, the researchers applied EFA to the data set to verify whether the five OFBR items are uniquely be explored. The researchers applied an orthogonal rotation of Varimax to evaluate the meaningful interpretation of the structure of the factors as generated from the data. We extracted a five-factor solution, with each one having an eigenvalue above 1 and explain 70.79 per cent of the total variance. The Kaiser-Meyer-Olkin measure of sampling adequacy was 0.881, which indicates a commendable level, as suggested by Kaiser and Rice (1974). Bartlett's test for sphericity was significant (X 2 = 3,757.242, p < 0.00). The researchers labelled the five new empirically derived factors SJME 24,1 as follows: OBF, OVS, OAA, OBE and OSR. All items under each construct provided factor loadings of more than 0.70, which is satisfactory as per Hair et al. (2009).
The following study explained the approach taken by the researchers to conduct and assess the validity of OFBR using CFA, whereas the current study applied Anderson and Gerbing's (1991) recommendation in conducting CFA (Table II) to establish the construct reliability and discriminant validity of the multi-item scales proposed. We constructed an SEM using AMOS to assess the relationships amongst underlying constructs. To test our model, we used chisquare value, which was significant. Moreover, the current study used several indexes to verify the overall fit of the model, GFI, TLI, AGFI, CFI, SRMR and RMSEA (Bagozzi and Yi, 1988). The result from CFA analysis also confirms that the composite reliability (CR) and average variance extracted (AVE) values were satisfactorily high for all latent factors (Table II).

Validity assessment (content (construct: convergent and discriminant)
Previous scholars have defined content validity as the extent to which the items of constructs or instrument covers the meanings of the concept that is being studied for a Notes: AVE, average variance extracted; OBF: online brand familiarity, OVS: online visual simplicity, OAA: online aesthetic attraction, OBE: online brand emotion and OSR: online social reputation. *All parameter estimates are significant at the 0.001 level Online fashion brand recognition particular research (Creswell and Creswell, 2017). Content validity aims to clarify the scope of a concept (i.e. OFBR) and determine whether the measure sufficiently reflects the domain of the concept (Bollen, 1989). It comprises the theoretical definition of constructs and a wellstructured literature review (Gomez et al., 2005). Building on the cited logic, the researchers confirmed the content validity of the measured items, which reflect the justified dimensions of BR from the perspective of online fashion.
In addition, the term construct validity is related to the degree to which the test items measure the constructs (i.e. OBF, OVS, OAA, OBE and OSR), which they were designed to measure. We assessed the construct validity of the scores obtained from an instrument by applying factor analytic techniques (Sun, 2005). According to Campbell and Fiske (1959), construct validity can be assessed using two approaches, namely, convergent and discriminant validity. The authors defined convergent validity as the degree to which multiple attempts to measure the same concept when two or more measures of the same concept should correlate highly if they are valid measures of the concept. Thus, the researchers tested the coefficients of CR and AVE for convergent validity. CR was used to assess the internal consistency of the measurement model. The results reflect that all constructs had high values of CR, which ranged above the benchmark of 0.6, as recommended by Bagozzi and Yi (1988). The results also suggest the high internal reliability of the data set. In addition, AVE values indicate the percentage of the variance of the construct by sampling an individual item. All constructs show high AVE values above the benchmark of 0.5, as recommended by Fornell and Larcker (1981) (Table II). In summary, the items adequately explained the variance of each construct. In addition, the EFA analysis results indicate that all five factors displayed unidimensionality, such that each set of items represents the intended concept and loaded on only one construct. Thus, the analysis provided evidence of sufficient convergent validity. According to Campbell and Fiske (1959), discriminant validity refers to the extent to which measures of the constructs (i.e. OBF, OVS, OAA, OBE and OSR) are relatively distinct, and their correlation values are not an absolute value of 0 nor 1. Similar constructs will produce high correlation values and indicate substantial collinearity between constructs, whereas unrelated constructs will result in low correlation values and demonstrate that the constructs are distinct from one another (Hair et al., 2009).
The current study conducted correlation analysis on the five factors of OFBR. The results highlight that all constructs are not highly correlated with one another because their coefficients are less than 0.70 (Tables III and IV). This finding implies that the constructs are unique and unrelated to one another, which in turn indicates discriminant validity. In conclusion, the statistical results indicated that the test of the measurement model, such as content and convergent and discriminant validity measures was satisfactory.  Tables III and IV) to examine the relation of the scale items to the OFBR construct. In this step, we aim to validate the second-order structure of OFBR by adopting the recommendation of Thomson et al. (2005). The study assessed the relationship between the scale items and the OFBR construct using CFA corresponding to three consecutive models.
Model 1 assumes that all 25 items load directly onto a single latent OFBR construct. Model 2 assumes five equally weighted first-order latent factors, labelled OBF, OVS, OAA, OBE and OSR, form second-order factor (OFBR) with no correlations permitted among the first-order latent factors. Model 3 is similar to Model 2, except that the first-order factors that modelled as correlated. This model aims to test the notion that the five dimensions (OBF, OVS, OAA, OBE and OSR) can be conceptualised as interrelated first-order factors loading onto a global OFBR latent construct. The results from CFA analysis explore that all three models show that each path is positive and significant, suggesting that each indicator contributes to the OFBR construct directly (Model 1) or to the first-order factors (OBF, OVS, OAA, OBE and OSR), which are themselves significantly tied to OFBR (Models 2 and 3). The study evaluates the fit indexes of each model to examine which model best fits the data. Besides, a CMINDF (minimum discrepancy divided by the degrees of freedom) statistic of less than 5 is considered adequate, with lower values being meritorious. For NFI, RFI and CFI statistics, higher values are expected, which is >0.90. According to these criteria, any of the three models is satisfactory and acceptable, because each possesses CMINDF statistics below 5 and NFI, RFI (relative fit index), and CFI (comparative fit index) statistics above 0.90 (Tables III and IV). However, the x 2 statistics used to enhance the comparison of the models that suggest Model 2 reflects significantly better fit (x 2 = 105.10) compared with Models 1 (x 2 = 365.47) and 3 (x 2 = 219.78). Thus, the study confirmed that Model 2 holds that OBF, OVS, OAA, OBE and OSR (five factors) that form the OFBR construct. Therefore, the researchers also confirm that the OFBR construct is formative via five dimensions.

Predictive, concurrent and nomological validity
The final stage of the scale development of OFBR examines the predictive and concurrent validity of the new construct. According to Sekaran and Bougie (2011), predictive validity refers to the extent to which the measures can predict a future criterion, which is theoretically justified. Therefore, the researchers used SEM to examine the relationships amongst the proposed related constructs of OFBR. This step aims to examine the predictive and concurrent validity of OFBR. Many scholars have examined and proved that consumers' online BR with regard to fashion products has a substantial influence on their BI towards purchasing from online stores (Kawaf and Istanbulluoglu, 2019). The current study measured BI towards purchasing from online stores to test predictive validity. The researchers adapted five items for BI from Hahn and Kim (2009) and Notes: CMIN/DF (minimum discrepancy divided by the degrees of freedom); NFI (normed fit index), RFI (relative fit index) and CFI (comparative fit index) statistics above 0.90 Zhang and Kim (2013). A five-point Likert scale ranging from 1 (strongly disagree) to 5 (strongly agree) was used to measure the constructs. The results of SEM analysis proved that a significant relationship exists between OFBR and BI towards purchasing from online stores (b (estimate) = 0.671, critical ratio = 4.785, p < 0.000). Thus, the significant relationship between OFBR and BI towards purchasing from online stores supported the predictive validity of the scale. The result from the fit indexes also suggest that the proposed construct is well defined and confirmed that online fashion brands are indeed a multidimensional construct. Figure 3 illustrates the standardised regression coefficients for the five factors, which constitute the online fashion brand scale. The result of the standardised regression confirmed nomological validity, which assesses the degree of the constructs as expected. All hypothesised directions support the nomological validity of the proposed construct.

Discussion and conclusion
Evidence from exploratory and empirical analyses suggests that the OFBR constructs are multidimensional as indicated by good fit and the five-factor model. Furthermore, the results of EFA and CFA maintained and justified the five unipolar categories (i.e. OBF, OVS, OAA, OBE and OSR). In addition, the findings embody consumers' fashion BR in the online environment. The researchers supported the evidence through extensive reliability and validity testing to reach the norms suggested by previous researchers.
The results suggested that consumers are highly sensitive to online fashion products in terms of familiarity and visual simplicity of the presentation of brands in the online environment. Consumers also provide significant weights on OBE, OSR and OAA in response to OFBR. These results are consistent with findings of researchers, that is, the coexistence of positive and negative feelings (Luan et al., 2019;Hanson et al., 2019). Further research is examined the effects of OFBR on BI.

Theoretical implications
This research contributes to prior literature such as Badura and Foltán (2010); Van Grinsven and Das (2016a, 2016b) and Washburn and Plank (2002) by providing a holistic scale that demonstrates the construction of OFBR scale. Our empirical study reports the relative importance of OFBR. It shows that all five constructs (OBF, OVS, OAA, OBE and OSR) should be holistically taken into account when measuring OFBR. Brands with higher levels of familiarity have higher levels of liking among both consumers and retail managers. In other words, well-known fashion brands may have an advantage from being better liked  (Colombo and Morrison, 1989;Laroche et al., 1996). In a similar vein, the online familiarity of a particular brand guide consumer attention to specific brands and develops confidence towards that brand to form an intention to purchase that fashion brand, which is also positively related to consumers' actual behaviour toward the fashion brand (Woodside and Wilson, 1985).
The implications of this study are significant for scholars in the field of online retail marketing. As the number of internet users continues to increase, the opportunities for online shopping brand continue to expand as well. Previous researchers have conceptualised quality and prices as the most essential elements for consumers (Bolton and Drew, 1991). However, recently, the situation has become complex, especially in the online retail environment, where consumers prefer a brand by considering multidimensional values, such as utilitarian and hedonic values (Grewal et al., 2003). We define utilitarian value as the overall judgement of a brand based on functional benefits and sacrifices. Thus, this value is relevant for a task-specific use of online shopping. For example, consumers shop online because of the convenience of locating and comparing quality merchants and evaluating price/quality ratios through recognition of online brands (Mathwick et al., 2001).
Conversely, the hedonic value is defined as the overall judgement of experienced benefits and sacrifices, such as entertainment and escapism. For example, consumers frequently shop online out of the appreciation of the experience rather than simply for task completion. On the basis of the two theories (i.e. utilitarian and hedonic values), the current research contributes to the existing literature on online fashion branding by empirically validating the OFBR scale, which can be used to measure the degree of consumers' recognition of online fashion brands. The OFBR scale validated in this work is the first scale of its type, which captures the concept of the online fashion brand retail sector, which has been ignored by existing studies on brand love, relationship between consumers and brands, attachment, involvement and loyalty scales (Batra et al., 2012;Hollebeek et al., 2014).

Managerial implications
The current study suggests that online fashion retailers should capitalise on the power of online BR, which shoppers use as internal information before making purchase decisions on the internet. Fashion brands that are recognised in an online environment and positively perceived by target consumers are more likely to be objects of purchase behaviour. Thus, local and international online fashion brand retailers can benefit from building OFBR using OBF, OVS, OAA, OBE and OSR to enhance the purchase behaviours of target consumers. The medium for online selling of fashion brands appears to be a strong potential marketing and distribution strategy for retailers with established online BR.
The findings also benefit the retail managers of online fashion brands who intend to develop a strong brand amongst target customers by applying the validated OFBR scale, which can significantly predict the consequences of online purchase behaviour of a fashion brand. The research outcome can assist brand managers in robustly understanding the nature of consumer perception in the formation of BR, which can improve the management of online fashion brands.
An information quality regarding OBF, OVS in representing the brand, OAA, OBE and OSR may provide customers with easy-to-read brand-related information or enable them to compare information with other fashion brands, which is essential for OFBR. The findings suggest that online fashion brand retailers should communicate their brand aggressively to optimise their respective BR. Domestic and international online fashion retailers should emphasise their fashion brand through all available media in online channels to compete in this industry. Park and Stoel (2005) revealed that consumers who recognise online apparel retailer brands are less likely to perceive risks and more likely to purchase from said fashion retailers. Therefore, using the pre-attained brand image and recognition will assist online fashion brand retailers in attracting more online shoppers. In addition, the dimensions of the validated OFBR scale may provide online fashion brand marketers with primitive strategic parameters to stimulate meaningful towards online brand experiences. Managers can gain knowledge of existing scores for OFBR amongst target customers and across dimensions by adopting the proposed scale. Above all, the proposed online fashion BR scale will be particularly useful for brand managers in international fashion clothing who want to grow a foothold in the fashion industry. Local and international fashion brands are offering foreign brands and aim to operate in other regions, such as Bangladesh, to satisfy the appetite for international clothing brands amongst local consumers. To capitalise on these advantages to the fullest, marketers for online fashion brands should understand the online BR of consumers. Thus, developing the OFBR scale is a significant step forward in this strategic direction.

Limitation and future research
This study comes with specific limitations and suggestions for future research. The major limitation is the reliance on non-probabilistic methods of sampling, which may not be representative of online consumers. The study is cross sectional and exploratory in nature. Therefore, further research is recommended for assessing the generalisability of categories of OFBR as found in this study across other product/service-specific samples. Moreover, the BR scale has been validated in only one country (Bangladesh) and only in the context of fashion brands. To render the model more generalisable, it should be tested across nations and other products/services. Furthermore, future research may focus on including additional online shopping dimensions that construct online shopping behaviour along with BR. For example, future research may investigate online brand interactivity, online brand devotion, customers' online value creation and e-sensory aspects of shopping. Hence, validating the OFBR scale will lay a concrete foundation for the validation of other comprehensive scales of online fashion brands for future endeavours.
