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. I dont know who came up with that, but it makes absolutely no sense whatsoever. I will use my own body as an example. I am 6 ft tall, and I have 37.5" arms. I have very big hands, and long fingers. My legs are shorter than my torso. All of this results in my arms reaching very far down. 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. Other people might have the exact opposite problem.
