This is a stretchy, wrinkle-resistant fabric. It's a FREE size, but I think it would fit like a size S-M. *Instant purchase is available.* Please refrain from purchasing if you are sensitive to used items, as I have worn it once. There are some red stains as shown in photos 3 and 4, but they are not very noticeable from a distance. It will be folded small for shipping, so please be aware of any wrinkles that may occur during that process.
