Vestiaire Collective is an online platform for buying and selling second-hand luxury fashion items, which was founded in 2009 by six knowledgeable individuals. On this site, all transactions are based on the premise of true identity verification and product inspection, eliminating the risk of buying fakes, mis-selling and mis-pricing. Since it is used or new clothes from KC, the site sells at a bigger discount, and it is also a better choice for those who want to sell their luxury goods.
