A yearslong bet on comfy bras and underwear has paid off for Japanese fashion retailer Uniqlo, as shoppers gravitated toward functional basics during the pandemic in a trend that looks set to continue in women’s wear.

Uniqlo, part of Fast Retailing Co. and founded by Japan’s richest man Tadashi Yanai, edged out bra specialist Wacoal Holdings Corp. last year to become the top seller of women’s intimate wear in its home market after doubling its market share in recent years, according to Euromonitor.

That came alongside broader gains made by Fast Retailing during the pandemic, which surpassed Zara owner Inditex SA as the most valuable clothing retailer in the world for a few weeks in February thanks to its focus on basics like sweatpants and T-shirts, as opposed to fast fashion.
