so i think that makes her a size 13, or would it be 17, women's? i did a search on google for size 13 and 17 women's dress shoes and got quite a few hits. one of the better ones...

i hope she can find something cause nothing can make a girl feel sexier than a knock-out pair of shoes. i wish her luck and lots of fun at prom.
