We all know what it’s like to fall head over heels for a brand and shop it until we’ve run out of the season’s trends (or cash). So when social commerce app Poshmark recently released a study on today’s most popular clothing labels, we were certain we’d see our go-to brands battle it out for the top spot— and surprise! It wasn’t what we thought. According to a press release, yoga brand Lululemon nabbed the title for the most in-demand label, followed by Gucci, Adidas, Free People and Madewell. (Surprisingly, our beloved Zara didn’t make the list!) Millennials comprise a majority of the app’s users, so you can be sure this says something about the latest generation’s shopping habits.
