If you think about it, the Olympics and New York Fashion Week aren't all that different. Both involve a lot of preparation and training, both demand that you bring your best to every appearance, and if you're not in the starting position (or just your seat!) when the event begins, you're totally disqualified.Another thing the two have in common? Just like making the cut for an Olympic team, getting to be a fashion A-lister pretty much has one-in-a-million odds. While we're not sure how to instantly fast track one's life from nights in a rental apartment to afternoons on a runway, the good folks over at BBC created a magical machine that'll do just that for your Olympic dreams. Using its newfangled HowMuchDoTheyWeigh.com, we grabbed approximate measurements* for some of our favorite fashion icons to see how they'd stack up to the world's best athletes.
