Lucky Sweater - Swap Closets

Lucky Sweater is a circular closet trading app where you swap secondhand fashion every Tuesday. It’s a free, community-first space for exchanging items you don’t use for new favorites—just cover shipping to swap. List items in your closet to trade, gift, or sell, and track outfits, share looks, and get dressed with fellow secondhand enthusiasts. Your closet can shift with your identity, size, and style as you trade and explore.

Join groups like Slow Fashion, Curated Thrift, Me Made, Vintage, and more; add in search of ISOs to tell others what you’re looking for; and use Save and Save Match features to curate your circle of items. Sustainers unlock perks like full group access, weekly perks, and enhanced protection for shipped trades, with an easy in-app shipping flow to keep clothes circulating and out of landfills.
