This is a properly fitting shirt, posted without iammatt's permission but I'm cazy like that. Notice with his arms almsot extended there is very little excess fabric in the sleeves. The cuff end right at the beginning on the hand. The armhole begins a bit higher on the shoulder then some may like, but I like this style. Chest, waist, very little excess fabric yet nt constricting either. I like my shirts a smidgen tighter at the chest and waist, but those are just preferences. The most important thing to me, is no excess fabric sticking out of the waist of the pants. Clean all around the belt line. I wouldn't wear an open collar shirt, I only wear button down collar shirts in that casual manner, but matt is very street and he can get away with it. There is no such thing as a "perfect" shirt as everyone has individual preferences as to fit and what have you but if your shirts can look like this all the time, you've done well.
