AOKI Ladies' Formal Wear One-Piece Dress With Jacket Ribbon Attachment OK This is a slim-fitting one-piece dress. I usually wear a size M, but this is a size 11 (Japanese size), one size up. I haven't used the ribbon much, so I'll include it as is. I've worn it a few times and it's been dry-cleaned and stored at home. The zipper is on the back. - Color: Black - Style: Suit/Formal - Accessories: Ribbon - Design: Dressy silhouette Thank you for looking.
