trying to judge the length of a jacket by how it looks in relation to you thumb or hands is a total waste of time. Â I dont know who came up with that, but it makes absolutely no sense whatsoever. Â I will use my own body as an example. Â I am 6 ft tall, and I have 37.5" arms. Â I have very big hands, and long fingers. Â My legs are shorter than my torso. Â All of this results in my arms reaching very far down. Â If I were to judge the length of my jacket by my hands or arms, I would be wearing a jacket that is several inches too long, I would look silly. Â Other people might have the exact opposite problem.
Phil, You point out a very specific, very real problem a lot of inexperienced shoppers are going to have: most salespeople do not know how to tell you what is correct specificially for your body. In general, salespeople do not perceive individuals. They will tell you the length of a jacket is determined by its relation to your thumb, and they will tug the jacket away from your chest and say, "See, perfect fit." All meaningless, unhelpful obfuscation. I think this: go to a good tailor and listen very closely and take notes as he fits you for a suit he is going to make for you. Not a template. Not something off the rack. Not something that exists. But something specifically designed for your body. Learn why he makes the choices he makes for you. If one were to do this, then one would know what--in an ideal setting--fits and looks best on their particular body. With this knowledge (the best weapon against ignorance, BTW), return to your RTW stores and judge everything you try on based on the criteria established by your trusted tailor. You will know the correct jacket length for you. The right arm length for you. The right waist suppression for you. Et cetera.
