This is a gently used vintage short jacket that could have been for over a dress. I don't have a matching dress to go with it. I think it is polyester. I don't know the size but it is 40" around and doesn't button up. The colors are teal blue, dark brown, gold, gray and black so you can wear several different color dresses under this cute jacket. It has been washed but not ironed. If you need more specific info please email me. I will happily combine purchases paid together within a 7 day period.
