Abstract
Purpose
Previous research suggests that many active females are not engaging in sports bra use, despite the positive health benefits. The aim of this study was to establish and compare sports bra use, preferences and bra fit issues for exercising females in some of the largest and most diverse global underwear markets (the US, the UK and China).
Design/methodology/approach
A survey covering activity levels, sports bra use and preferences, bra issues and demographics was administered via Qualtrics and completed by 3,147 physically active females (aged ≥ 18 years) from the US (n = 1,060), UK (n = 1,050) and China (n = 1,037).
Findings
In general, participants were 25–29 years, 121 to 140 pounds, 34B bra size and pre-menopausal. “I cannot find the right sports bra” was the most frequent breast barrier to exercise (25.4%). Three-quarters of women wore a sports bra during exercise, with significantly higher use in China (83.9%), compared to the UK (67.2%). A third of all participants reported sports bra shoulder straps “digging into the skin”. Sports bra preferences were: compression sports bras with a racer back, wide straps and thick straps in the US and the UK; thin straps in China and adjustable straps and underband, no wire and maximum breast coverage in the US and the UK, including nipple concealment and with padded/moulded cups.
Originality/value
Information provided on differences in sports bra use, preferences and bra issues across three major global markets could be utilised by brands and manufacturers to optimise bra marketing and fit education initiatives and inform future sports bra design and distribution strategies.

Abstract
Purpose
The purpose of this paper is to measure the breast volume of a large sample of women and their corresponding correctly fitted bra size, in order to demonstrate the range of volumes within each size and the variation amongst different bra sizes.
Design/methodology/approach
Breast volume of 104 women was measured via water displacement and was compared to their professionally fitted bra size, in the one style and brand of bra.
Findings
The mean breast volume of the left and right breast was 642 and 643 ml, ranging from 125 (size 10A) to 1,900 ml (size 24DD). The average professionally fitted bra band size was 12 (range size 10‐24; Australian sizing) and cup size was DD (range A‐G). A range of breast volumes was found to correspond to the same bra size and the volume of any one cup size was not homogenous amongst different band sizes.
Practical implications
Appreciating the range of breast volumes that correspond to each bra size is important in terms of both bra structure and design in order to provide adequate breast support. The large variation in cup volumes associated with different band sizes suggests women should not consider themselves to be an isolated cup size, but rather a combination of a band and cup size.
Originality/value
This is the first study to publish normative breast volume data, and the corresponding correctly fitted bra sizes, for a large sample of women. This is important information for bra design and to assist women achieve correct bra fit and support.

Abstract
Purpose
The breasts are mainly fatty and connective tissues with no muscles that directly support them, so wearing sports bras is one of the most effective means of alleviating the discomfort of breast movement and potential injury during vigorous physical exercise. However, the design and development processes of traditional sports bras are time-consuming and costly. Hence, a novel method of simulating the static contact pressure between a sports bra and women’s body based on the finite element (FE) and artificial neural network (ANN) models is developed in this study to contribute to the design considerations of sports bras.
Design/methodology/approach
Three-dimensional FE models of a female subject and sports bras with different fabric properties are developed to determine the amount of contact pressure exerted onto the body. The FE results are then verified by measuring the amount of pressure exerted by the sports bra on the skin with pressure sensors. The Taguchi technique is used to effectively reduce the number of trials from 625 to only 25 cases. These 25 results obtained through FE modelling are then used to provide the training set for the ANNs. Finally, a comparison between the FE and ANN results is carried out.
Findings
A novel model of the static contact pressure between a sports bra and human subject based on the FE and ANN methods is presented in this paper. The root mean square error values show that there is only a small difference between the FE and ANN results.
Originality/value
The ANN function established in this study can be used to predict the mechanical behaviours of breasts and has a fundamental impact on the computer-aided design of functional garments in general.

Abstract
Purpose
The purpose of this paper is to clarify the relationship between dynamic clothing pressure of women's sports bras and heart rate variation indexes during playing basketball.
Design/methodology/approach
Totally, 35 healthy females aged between 20 and 24 were employed as subjects. Their heart rate variability (HRV) data and the clothing pressure values when wearing sports bras of different bust sizes during playing basketball were measured using Polar RS800CX heart rate monitor and Flexi Force201 thin film type pressure sensor with MFF series pressure test system. Their subjective comfort evaluations were conducted by five-point Likert scale. Grey correlation analysis is used to determine the correlation degree of heart rate variation indexes and subjective comfort evaluations to identify the indexes preferably associated with subjective comfort. Multiple regression analysis is applied to investigate multiple correlations between pressure of test points and the indexes selected above.
Findings
Combined subjective comfort evaluation with objective HRV evaluation the heart rate variation indexes preferably associated with subjective comfort of these bras were identified, which includes mHR, mRR, RMSSD, pNN50. By the relationship between dynamic clothing pressure and the indexes above, this study finds that the clothing pressure of the chest area during basketball exercise should be controlled in the range of 2.01-4.74 kPa.
Research limitations/implications
The subjects of different body type should be taken into account. Further, the mathematic models from this study show low R2-value so the models should be provided more reliable prediction.
Originality/value
The present study indicates that there is an inevitable connection between heart rate variation indexes and subjective comfort of basketball sports bras and creatively points out that heart rate variation indexes can partly assess the comfortable clothing pressure. The study can offer theoretical basis for sports apparel industry to develop the comfortable basketball sports bra.

Abstract
Purpose
In addition to the psychological differentiation of older women, ageing has numerous effects on the breast, influencing the volume, density and constitution of the tissue. It is currently unknown how these changes may affect bra requirements and bra consumer behaviour. The purpose of this paper is to explore factors of importance in bras in a cohort of women aged 45 to 65 years, whilst considering purchasing behaviour, brand loyalties and self‐image.
Design/methodology/approach
Following a grounded theoretical perspective, this study was exploratory in nature, including a mixture of five semi‐structured interviews and two focus groups with women, aged 45 to 65 years, to discuss bra habits, considerations, and influential factors of purchasing. Data were content analysed with additional frequency analysis.
Findings
The paper provides five key dimensions within which older women focus their attentions when purchasing bras. These are aesthetics, comfort, practicalities of bra purchase, breast support and psychological aspects. Participants purpose their bra requirements to be multifaceted and changing with increasing age.
Practical implications
Bra manufacturers and distributers may need to consider these factors when marketing towards an older population of women, to optimise products and subsequent sales.
Originality/value
The paper advances the literature by providing fundamental information on the key areas of consideration for older bra consumers.

Abstract
As a supply chain management initiative, category management has to date been the almost exclusive preserve of the grocery sector and, within that sector, limited to food categories. This paper proposes that the fashion industry might usefully follow the grocery industry's lead and implement category management. A comprehensive review of the literature on category management highlights the opportunity for fashion marketing to consider the potential of category management, and the specific research gaps. In operationalising the subsequent research objectives, the paper reports the results of exploratory, in‐depth consumer research for a particular category of intimate apparel. The managerial implications of these findings are then discussed in the context of the established eight‐step category management process. The overall tentative conclusion of this study is that as a consumer‐oriented joint planning tool, category management offers retailer‐supplier partnerships in the fashion industry an important adjunct to the industry's quick response methods. The paper closes with an agenda for future research.

Abstract
Purpose
The purpose of this paper is to explore a novel breast volume measuring method by mesh projection based on three-dimensional (3D) point cloud data.
Design/methodology/approach
Mesh projection method, a rapid and accurate method to calculate the volume of models described by triangular meshes, was transplanted to calculate breast volume based on 3D point cloud data derived from a [TC]2 3D scanner. A simple landmarking procedure was developed to decide breast boundary. Breast volumes derived from mesh projection method were compared to the results of water displacement by statistical analysis to validate its accuracy.
Findings
A novel breast volume measurement method is developed based on mesh projection method. By comparison of water displacement, mesh projection method is proved to be accurate to calculate breast volume. Furthermore, a simple and standard breast boundary landmarking procedure is established, which avoids the arbitrariness of the definition of breast boundary and improves the repetition of landmarking.
Practical implications
A simple and convenient tool is provided for bra industries to rapidly and accurately measure breast volume.
Originality/value
Mesh projection method is primarily applied to determine breast volume based on 3D point cloud data. Meanwhile, a simple and standard breast boundary landmarking procedure is put forward.

The purpose of this paper is to examine the effect of celebrity-advertising context congruence on transferring a celebrity’s image to a brand image.
Abstract
Purpose
The purpose of this paper is to examine the effect of celebrity-advertising context congruence on transferring a celebrity’s image to a brand image.
Design/methodology/approach
This study investigates the effect of the advertising context, which is the background of the ad provided by the vehicle carrying it, in transferring a celebrity athlete’s image.
Findings
The results indicate that the presentation of a celebrity athlete in an advertising context that is congruent with the professional expertise of the athlete enables the more effective transfer of the athlete’s image to the brand’s image compared with the incongruent advertising context. In addition, the findings suggest that image attributes perceived as belonging to the professional expertise of an athlete are transferred more effectively by a context-congruent advertisement, while image attributes based on the sociocultural influence of an athlete show no difference in image transfer based on the advertising context.
Originality/value
Although the advertising context has been thought to influence advertising effectiveness, no specific research has thus far analyzed the relationship between image transfer and the advertising context in the sports marketing literature.

Abstract
Purpose
The purpose of this paper is to apply the theory of perceptual image to clothing, study the effect of bra components on the perceptual image of Chinese female consumers aged 18 to 27, explore the relationship between them, promote the computer-aided bra design to be more rapid and accurate and meet consumer's needs better.
Design/methodology/approach
In this paper, cognitive psychology and mathematical analysis methods were used, and two experiments were conducted. A reaction time experiment was conducted based on 3D virtual bra samples, proving that bra components have an effect on the consumer's perceptual image and obtaining a revised bra component design indicator system by multi-dimensional Scaling (MDS). A projection experiment was conducted to study what kind of relationship exists between the two, and a prediction model was constructed by the quantitative I-class theory.
Findings
It is found that bra components have an effect on perceptual image of Chinese female consumers aged 18 to 27. A total of five important components (cup area, center front height, torso width, side wing width and center back shape) that affect the consumer's perceptual image were identified by MDS and references analysis, and then a bra perceptual image space composed of five pairs of words was constructed by subjective evaluation and cluster analysis. What is more, a prediction model was obtained by the quantitative I-class theory; after testing, the model can visually and effectively predict consumer's perceptual image according to bra components indicators, which provide a convenience for the positive design of bras.
Research limitations/implications
In this article, the authors just studied bra components, but did not take fabric, color and other factors that also affect the perceptual image into consideration. Further research can use this method to study other important influential factors as well as their comprehensive impact. Also, the subjects are Chinese young women; consumers of other age or from other countries are not involved, and more extensive research can be done in the future.
Practical implications
The bra component indicator system can help to build a more systematic and clearer bra design library, which provides convenience for designers to search and use them quickly, improving the efficiency of bra design. The prediction model is also helpful to bra designers and companies. When they already design a bra, they can use this model to predict consumer's perceptual image, thus carry out more accurate market positioning and promotion. When they want to satisfy consumers or design a specific effect, they can also refer to this model to reverse design of components. In general, the outcomes of this paper can help companies to quickly establish a computer-aided bra design system, which is conducive to designers to accurately design and better meet market's needs, and the method is also a good attempt to apply the theory of perceptual image in psychology to clothing and can be extended to other relevant fields in the future.
Originality/value
Based on cognitive psychology, this paper attempts to apply the theory of perceptual image in psychology into clothing and takes bra as an example to study the relationship between bra components and consumer's perceptual image. The prediction model constructed here is conducive to the development of bra design and to meet personalized needs of consumers. This method can also be extended to other fields in the future.
