Because my brother is so skinny he still shops in the boys section. He's 28. So I imagine it can't be too hard to find smaller than average shoes.
The only good thing about having to wear children's sized shoes is that (a) they tend to be cheaper, and (b) I get to wear cute little red glittery shoes with bows on them like Dorothy from the Wizard of Oz.
But, sometimes when I walk past women's shoe shops, I groan 'cause there are so many women's shoes that I really, really like.
