Vintage Blue Military Style Dress

Amazing vintage dress! It’s giving off a military vibe to me. Two side pockets hidden inside of large pleats. One dramatic pleat on the back. It can be worn as a dress or a light weight jacket! I’m 95% sure this is cotton! Measurements taken laying flat and are approximate P2P: 20.5” Length: 36.5” Sleeve Length: 19.5” J100
