Chanel silk dress! Fits like a 2 - label says 42

Genuine Chanel vintage silk slip knee length dress! Perfect LBD if you can fit into it! Dress on the runway (slightly longer)worn by Karolina Kurkov in the Spring 2002 ready to wear show in Paris. Please note belt and jewelry are not included. Now the tag for this says size 42 which is supposedly a 10/12. I’m normally a 6 and couldn’t get into it. Measurements on this dress are roughly 32 bust, 26 waist, 34 hip! From top of shoulder strap to bottom 36”. Condition is excellent. See photos.
