This reversible item features a boa-like material on one side and a nylon-like material on the other. I've worn it about 2 or 3 times. It's a size M, but it has a relaxed fit. I have a lot of outerwear and I don't remember where I bought this. I'm a private seller, so there may be oversights. Please understand (_ _*)) ☆I'm also listing this on other sites, so I may suddenly remove it if it sells.
