I love the idea. As a tall slender person, I'm usually in between sizes and things are never right. For this along with every other personal item, I hope manufacturing on demand gives us all a return to personal customization.
One thing keeps bugging me though. Home page, slide one, white polo. I don't think that shirt fits right. It looks like it's too narrow either across the chest or in the shoulders and that is causing it to pull up on the buttons in the center and creasing the front of the shirt and the bottom of the buttons. Maybe I'm just being a know it all programmer with no fashion sense, but I don't think I want my polos to fit like that.
