Ordered a med for my son, who's 6'1", 150 lb. (Yeah, slim we know) This coat looked slim and with longer sleeves from photo. I checked the size chart (Amazons) which Levi doesn't provide one of their own. With med, it fit his shoulders ok, slightly tight (they are wide for a slim boy), the body of coat was boxer than it looks, but length was good. It's the sleeves!!! For a med size the length was only 25 1/2". I am disappointed because the style and quality of the coat are awesome. Hopefully this will help to find the right fit for others. I have to keep shopping for another ...sigh
