  2. Return policy

    Read it before you pay. Terms differ: Collector Square gives 14 days, Vestiaire Collective gives 14 days only when the seller is a professional, and none when the seller is a private person.

These checks help you compare a listing with the official facts. They do not show that a bag is genuine, and we do not authenticate anything. Buy from a seller that says who authenticates and what happens if an item is not authentic.

How we check prices

  • The boutique price is the public price the brand publishes on its own website: we use it only as a benchmark to measure how much you save pre-owned.
  • Each price carries the date we saw it, on the official page or in an archived copy, never the date of an increase announced elsewhere.
  • When a brand has one price across the euro area, the chart follows four reference markets: France, Italy, Germany and Spain.
  • Periods we did not check are drawn in a lighter grey, and we never fill them with an estimate.
  • Every price in the table under the chart links to its source.
