The fashion and athletic wear brand Fabletics is the latest retailer to help customers clean out their closets.

Fabletics is entering the booming resale market in collaboration with online resale platform ThredUp. Fabletics will leverage ThredUp’s resale-as-a-service program to offer the reseller’s Clean Out Kits to its customers, both online and in-store.

Fabletics customers can fill the kits with apparel, shoes, and accessories from any brand and ship them to ThredUp for free. ThredUp pays the seller for items that meet quality standards in the form of Fabletics credits, which are automatically added to the seller’s Fabletics account and can be redeemed online or in-store for up to 12 months.

“Fabletics’ move into resale is part of a broader strategy to become more environmentally conscious,” said Adam Goldenberg, CEO of Fabletics. “This deal with ThredUp is a win-win for us and a good step into circularity – our customers now have a hassle-free way to give their unwanted clothing a second life, while gaining perks to refresh their closets, and we at Fabletics are excited to play a more meaningful role in creating a more sustainability-conscious fashion industry.”
