90s Chantal Thomass Button Dress

Rare and unusual dress by Chantal Thomass from the 1990s. The dress has a genius detail -- the collar is detachable by a series of buttons. The collar can be removed and worn separately (as seen in the photos) and the dress can be worn separately as well. The dress is made of a very stretchy ribbed material and can fit a variety of sizes. Seemingly unworn and in pristine condition.
