The purpose of this paper is to discuss how brassiere manufacturers develop new designs for bra products, suitable for individual consumers, through consumer codesign.

New product design that relies on conjoint analysis algorithms can depict multidimensional attribute profiles, such that consumers' choice behavior reflects their preferences and overall judgment of the profiles. This statistical technique provides a means to codesign and customize bra products and thereby enhance the overall bra design process.

Bra products codesign suggests goals such as attractive appearance, shoulder strap style, vivid/mild color, elegance/sexy lace, comfort/practicality, fabric, lining, comfort/attractive appearance, neckline design, comfort/excellent function cut, sewn cups, and generous quantities. The most preferred combination of attributes for all respondents is a cotton/cotton blend fabric, seamless bra that offers a detachable shoulder strap, lavender color, a two‐strap style, lace details, and a low‐cut plunge neckline. The paper illustrates consumers' bra awareness attributes, codesign approach, and individual optimum individualized bra designs.

The results provide a useful source of information for product managers, who should consider the use of codesign to design the best products for individual consumers and decrease the risk of design failure, as well as promote consumer loyalty and satisfaction toward the product.

The paper provides a unique method to understand the new product codesign structure and make bra product design decisions that integrate optimum individualized design.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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).

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).

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.

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.

States that bra design is a highly specialized process requiring a combination of design creativity, precision pattern making skills and a detailed knowledge of fabric performance. Although there is substantial published material cataloguing the historical origins of the garment, there is little information documenting the bra design and manufacture. Examines the design process, following a survey of professional designers. Describes a common framework along with the variations in individual working methods. Emphasizes the high dependence on heuristic knowledge and the reliance on physical prototyping in the design cycle.

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.

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.

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.

A simple and convenient tool is provided for bra industries to rapidly and accurately measure breast volume.

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 aim of this paper is to explore a method of predicting the amount of personalized bra cup dart in the 3D virtual environment for supporting the made‐to‐measure research of the optimum fitted brassiere pattern design.

Very useful enhanced FFD (free‐form‐deformation) techniques used in both computer animation and geometric modeling were skillfully transplanted to the female breast model deformation. Meanwhile, on the basis of 3D scan and surface modeling technologies, the realization approach of the abstract female breast model library focusing on the individual variations of shapes and sizes was presented. Then according to the principle of isometric area and flabellate segments, the personalized bra cup dart quantity and its distributive information were provided by 3D‐2D transformation.

The paper finds that personalized female breast shapes and various aesthetic breast forms sculpted by different bras could be interactively simulated. Accordingly, the amount of corresponding individual bra cup dart and its distributive information were provided. The cup darts were mainly distributed below the bust line. Moreover, dart shapes were curvy.

The principles of virtual breast library construction and 3D‐2D transformation are also suitable for other parts of the human body such as buttocks, abdomen and, etc. for intimate apparel research.

The method of predicting the personalized bra cup dart quantity based on the 3D virtual breast model library was delivered for the first time. The novel findings provided an important guideline for designers to improve the well‐fitted bra pattern design technique. Furthermore, it would reduce the manufacturing cost without keeping physical dummies.

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.

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.

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.

Bra manufacturers and distributers may need to consider these factors when marketing towards an older population of women, to optimise products and subsequent sales.

The paper advances the literature by providing fundamental information on the key areas of consideration for older bra consumers.

This paper aims to explore the application of the business risk audit (BRA) approach within non-Big-4 audit firms in the USA, the UK and Canada. This paper focuses on the motivation for adopting this approach for non-Big-4 audit firms in the three countries, and the advantages, disadvantages and aftermath of applying this method.

A combination of qualitative and quantitative methods to obtain the data necessary to address the research questions was used.

It is found that non-Big-4 audit firms in the three countries have adopted BRA; their motivation was primarily to follow the standards in each country, and the general trend in the industry. The advantages identified are consistent with previous research; a direct benefit was noted for audit effectiveness and risk management for both clients and auditors. One major disadvantage of applying BRA is the cost burden to both the audit firm and their clients. Some of the interviewees claimed that this method is better suited to large firms and large audits.

This is an innovative study that addresses a contemporary auditing issue. The majority of the audit research studies concentrate on the big audit firm practices; this study is the first to examine the application of audit practices within smaller audit firms.
