I start with the third button from the bottom before moving up to the top, after that I fasten the very bottom button, second from the top, second from the bottom and third from the top. At that point, I'm usually pretty exhausted so I go back to bed for 2 hours.
Start with the third from the top and work my way down. Then decide how much sexy the ladies can handle that day, and maybe button the second from the top.
I suppose you apes don't even do a military tuck when you tuck your shirt in. You disheveled baboons!
