I bought this and the melton pea coat in XL this one is a little loser in the shoulder/chest area. I'm 6' 220lbs and i have a very difficult time finding jackets that fit they are always too tight in the chest and way to big in the stomach area. this one is no different. I was hoping for more of an athletic fit. I wear a 48 long in a sports coat/suit so take my fit with a grain of salt. i think this would be good for someone with a 46. the arm length is great as long as i don't raise my arms more than a few inches
