Conventional apparel was built around a body that could button, reach, grip and stand without assistance. For the large share of the population whose bodies did not meet those assumptions, clothing was a problem managed through specialist channels or post-market alteration. Retailers including Tommy Hilfiger, Nike, Zara, Marks & Spencer and Kohl's are now integrating adaptive lines into standard stores, reflecting commercial recognition of a market failure the industry long declined to name.
