Sleeve Length: Short sleeve Season: Summer Pattern/Design: Other I bought this a few years ago and only wore it when I tried it on. I haven't had many opportunities to wear it, so I've been storing it at home. It's thin, and it also comes with a lining to wear under a dress! It's wrinkle-resistant. The waist tie is designed to be tied at the back, which is a slightly unique design. The size is 38. I think it's probably a size M.
