I am 56, sort of medium/husky build, about 175 lbs. and the Small fit just right. I wanted the jacket to fit tightly like it does in the movie. My major complaint is that my Winter Soldier arm from SoloRoboto Studios doesnt fit through the arm hole. I had to seam rip the bottom part of the hole to get the cybernetic arm to fit through. Also, the jacket takes acrylic paint well, as I wanted the brown texture shown in the movie. Overall, its a good jacket for the price.
