Tradesy is an online resale marketplace founded in 2009 by Tracy DiNunzio in Santa Monica, California, focused on making it easy for women to buy and sell authenticated pre-owned fashion. The platform specializes in designer and contemporary women's clothing, handbags, shoes, accessories, and wedding items, serving as a trusted destination for luxury resale. Tradesy was acquired by Vestiaire Collective in 2022, expanding the combined platform's reach in the North American market.
The platform was notable for its seller-friendly approach, providing prepaid shipping kits and a straightforward listing process that made it easy for individuals to sell items from their closets. Tradesy's authentication team verifies designer items to protect buyers from counterfeits, and the platform offers returns on items that are not as described. The marketplace carries pre-owned pieces from sought-after brands including Chanel, Louis Vuitton, Prada, Gucci, and Celine, alongside contemporary favorites. Tradesy helped pioneer the concept of making luxury fashion resale accessible and mainstream.
