1. VESTIAIRE COLLECTIVE
The most famous online platform for luxury second-hand clothes. I tried to purchase clothes via Vestiaire Collective twice but never succeeded because sellers did not update their listing. They sold the clothes somewhere else but kept the listing live. Nevertheless, I got my money back instantly.
