Clothes worth keeping should keep moving.

The best things in most wardrobes were made decades ago, and most of them are sitting still.

Trademarche is a marketplace for authenticated vintage and designer pieces, built around trading. Buy outright, sell for cash, or swap: trade a piece you’ve finished with for credit toward one you haven’t found yet, or offer it straight to another owner.

Every piece is examined by a specialist in its category, graded honestly and photographed as it is. Swapping keeps the good things in circulation, and keeps the value of a wardrobe in the wardrobe.
