Left is right

Working on the apparel category, one of the first things that struck me was that everything is made for right handed people. Why is it that the pocket and the button holes are to your left? It is only to facilitate the right hander. Why can't they come out with a separate line of clothes that is designed specifically for the southpaw? Maybe it does not make much business sense (considering that most of the people would be right handers), but it sure is a thoughtful gesture.
