Tomlin told POPSUGAR that Reformation, Lululemon, Anthropologie, and Free People are among some of the best-selling brands on Thredup right now. Over the past month, the site has seen a spike in comfortable basics like t-shirts and leggings, while workwear and occasionwear categories have declined. "Sales of leggings were nearly 30 percent higher on average during the last two weeks of March compared to February," she said. "Interestingly, blouses remain popular as many women embrace the 'fashion mullet' look to balance comfort with back-to-back conference calls from home."
