Very disappointed with the sizing on this jacket. I normally order a 2 extra large tall in jackets and shirts. This item did not have that size to select from but it did have a 3 xl so my thinking was that it would probably work.  It turned out to not even be close. The sleeves are too short and too small in diameter, the jacket is too short, the shoulders are too narrow and the jacket will not button. It's undersized in every aspect. I'm guessing that it probably would work well if a person wore a large/extra large but certainly not any larger than that. The tag in the jacket says 3 extra large, but it most assuredly is not.
