I dunno, I would be concerned that it would add bulk. The concept is unique, but the skinny sleeves with boxy shape and puffy looking shoulders could lead to an inadvertent linebacker effect. Just my two cents.
i don't like how it looks when it's buttoned up. i like it open and don't mind the sleeves except i don't know how practical it would be to have a coat with short sleeves that is supposed to keep you warm.
