I ordered this when it last went on 'final sale' ... I am usually a large in most shirts, jackets etc. The L size in this was, I would say, on the very very bottom of the spectrum of what I would consider Large. It fit like a slim cut tshirt (high arm holes, very short torso (and I already have a short torso for a tall guy). It's also incredibly thing despite how it looks; wind whips right through it... not a winter coat. I don't even wear mine anymore, but I still think it's a great looking thing and can work for you too, if you buy a size larger and wear it appropriately.
