I bought this because I one Of my guy friends did and I sort of was obsessed with it!! Even thought its mens I decided to take a risk and buy one even though Im a lady. It actually turned out AMAZING!! So if you're a women looking at this jacket DO IT!! I normally am a womens medium, I have a small waist and a bigger chest and I fit in a XS, with room to comfortably zip up the zipper and the arms are great. I love this jacket. So happy I bought it!
