Vestiaire offers made by buyers are not binding. You can accept an offer from a buyer and the buyer has 24 hours to purchase the item. Multiple times I've had buyers make an offer that I have accepted and they end up not purchasing the item. Vestiaire should make offers binding so that buyers on make serious offers. Also, Vestiaire sends emails to potential buyers telling them if a seller has accepted an offer for a certain price. Seems like that should be confidential. Sellers don't seem to be protected on this site. I don't plan to sell anything else on this site in the future.
