Sophie Hersan had worked as a stylist before she started Vestiaire Collective. In 2009 she teamed up with Fanny Moizant, who had just finished a degree at a French fashion institute.
The two launched a website called Vestiaire de Copines in Paris. It opened with about 3,000 pre-owned items from friends and family.
The site was renamed Vestiaire Collective in 2012 and opened in the UK that year. It reached the US in 2014 and became a unicorn in 2020. It earned B Corp status in 2021 and bought Tradesy in 2022.
Investors include Kering, Tiger Global, Condé Nast, SoftBank and Eurazeo. In 2025 Bernard Osta became CEO, and Moizant left in January 2026.
