Fanny Moizant finished a degree at a French fashion institute and joined Sophie Hersan, a former stylist. In 2009 they launched Vestiaire de Copines in Paris with about 3,000 pre-owned items from people they knew.
The site was renamed Vestiaire Collective in 2012, when it launched in the United Kingdom. The United States followed in 2014, Europe in 2015, and Hong Kong, Singapore and Australia by 2017. Kering, Conde Nast, Tiger Global, SoftBank and Generation became investors.
Vestiaire became a French unicorn in 2020 and a B Corp in 2021. It bought the American resale company Tradesy in 2022, and in 2022 and 2023 it banned a first group of fast fashion brands. A February 2024 crowdfunding round raised about €3.5 million.
Bernard Osta became CEO in October 2025. In January 2026 Moizant announced her departure after sixteen years. The company now operates in more than 70 countries.
