This is a consignment item on behalf of my mother. She bought this at the recommendation of a shop assistant at the time, but it was a little too big for her, so it has been sitting in the closet for a long time. It's labeled as a size S, but it runs large. It has a lot of stretch, so it seems like it would fit someone who wears a size 7-11 (in Japanese sizes). It's a rare reversible design. It has a denim-style print on one side and a gray lace-like floral print on the other. Polyester and polyurethane. Purchased at Mitsukoshi (department store). Authentic item. Used a few times. Stored for a long time. The material tag has been cut off. Thank you for looking.
