On Earth Day, Stitch Fix rolled out a social campaign across Instagram and TikTok, promoting a “closet cleanout.” The content encouraged customers to send in their pre-loved clothing using ThredUp Clean Out Kits in order to earn Stitch Fix credit. The messaging focused on reducing fashion waste, and making space for fresh styles.
