I looked at the size chart before I ordered, and thought I better order a large based on the chest size. I wanted it a bit baggy, so I thought I was in the clear. When I got it out of the bag, I thought they shipped me an XXL by mistake. Crazy sizing. Can't provide much more info since the sizing is so off. I think I need a small if I exchange. If you usually wear small, I don't think this will work for you.
