So, what if you come along a girl that is taller than 5 foot 2, weighs more than 90 lbs, and you have to go all out and buy a large? Better yet, what if her boobs are really big? Then your'e screwed....or not screwed I guess because you can't get the chic on your bike to take her home for a lay. Sorry, off on a rant. I can't fit one boob into an a small, much less and XS! And I don't consider myself to be a fat chic.
