Help!

Can anyone tell me where I can find varsity style jackets in women's sizes? I got one very similar to this for Christmas - it's a medium and it's too big.
It sucks because they don't make anything smaller than that size in the men's shop - and they don't have ANY in the women's or kid's shops.

I really want to replace the Christmas one with one that fits, but I can't find it anywhere!
I'll be so happy and give props to anyone who can help!
