How about looking at what people in magazines wear who don't have much of a chest - there are lots out there, think people like Keira Knightly.
I have the opposite problem, so many things I can't wear because I have too much. Would love to be able to wear nice delicate little tops, strapless, halterneck etc... go without a bra to get tops which fit everywhere, not just my chest :)
You're only young aren't you so you may still grow. I used to despair of having a chest and I'm not a 36G!
