With the recent rise of resale apps like Depop and Poshmark, the idea of selling old clothes online is becoming more fashionable. Many people have turned clothing resale into a lucrative side gig or even a full-time job, gaining thousands of followers and making dozens of sales per week.

The secondhand-clothing market is projected to more than triple by 2030, according to a 2021 study by reselling platform Mercari and research firm GlobalData, as more fashion enthusiasts clean out their closets and search thrift stores to find valuable pieces to resell.
