On Girls Bra Design for the Demand of User

Good bra design has an important impact on the healthy development of women’s chest, especially on the breast health of adolescent girls. This paper selected Guangzhou, Guangdong Province, China for field interviews and questionnaires to collect girls’ needs and expectations for bra design. Principal Component Analysis (PCA) was used to select the demand factors that have a greater impact on bra design: chest protection, corrective posture, size standards and pain relief, and the weight ratio of different factors was defined. It is found that protecting the chest and correcting posture are the most important requirements of bra design for adolescent girls. Establishing the size standard of underwear for adolescent girls and alleviating the pain during development are important complements to the optimization strategy, which can provide basic data support for further optimization research of underwear design for adolescent girls.
