This is a two-piece set consisting of a dress and a jacket! The color is black, and the size is 11. I'm selling it because I've outgrown it! I've only worn it once. It's a short-sleeved dress, so you can wear it on its own! You can also wear it in winter if you put on the jacket. The ribbon on the jacket is removable! It has been stored at home, but it's clean with no stains or scratches! Please ask if you have any questions.
