Obviously the way these fashionistas wear there jackets is way too short...
but I secretly, shamefully prefer shorter jackets on myself.
-I have somewhat odd proportions, and (in my mind) short legs (33-34" inseam on a 6'2" man). Shorter jackets help even out my proportions, whereas properly sized and longer jackets make me look like a giant torso with little gorilla legs.
-It's easier for me to find jackets that fit me in the shoulders and chest when I don't have to worry so much about finding longer coats. I have a 35" chest, and am very lean with a long neck. I don't prefer slim jackets because it's a fashionable look, I like them because if I wear anything bigger I look like child in his father's suit.
Sorry, I love the cropped look. It enables a relatively average height guy like myself to appear a bit taller. It also accentuated my behind (which I - and my wife - believe to be very attractive) and why shouldn't I want to make myself look as good as possible?
