Size: Men's XS (SS) I am a woman, usually a size M, but this fit with room to spare. I bought this at an outlet mall in the UK, but it doesn't fit, so I'm selling it. I bought it six months ago, and it's a men's XS size. I am a woman and usually wear a size M, but I was able to use it without any problems. The lower part of the down jacket is slim-fitting, so it makes you look slimmer. It's almost new, but as marked in the photos, there are a few spots where the filling might come out slightly, so please be aware of this before purchasing. The filling doesn't actually come out, and there are no issues with wearing it. Here are the approximate measurements (taken by hand): Total length: 66cm Body width: 47cm
