The transition of sports bras’ uses, from an active lifestyle to resting activities, requires adaptable comfort properties of the design (Quinn, 2010). In the current age of technological revolution, the sports bra industry is still not offering an adaptable and responsive sports bra, which supports the body during high impact sports while feeling soft and comfortable during rest (Hansman, 2017). Moreover, the current commercial sports bras are made using all synthetic yarns and using garment dyeing processes that are not ecological sustainable (McCann, 2005).Thus, the two-fold purpose of this study was to: (a) analyze the materials and processes used in the product development stages of seamless sports bras, and (b) propose a biomimetic design solution for a seamless sports bra that offers responsive breast support during running versus resting activities.
