I am buying some suits and need some advice. I have never purchased a suit before. I have been looking at JAB, as they seem to be one of the best stores in my area and are in my price range. I am 6' 4", 170 lbs, and have a skinny but athletic build. Jacket size is a 41R, and 32" waist on pants. Do I need to specifically request slim fit suits, or will they have no problem fitting an OTR suit to me? Thanks.
