If I could pick my top three it would be:
1. hair - it's long, straight and verrrrry dark (natural of course!). I don't really do anything special to it besides brushing it because I really like the way it looks naturally. Guys have told me that it makes me look "exotic" because a large majority of females here are blond
2. eyes- deep & mysterious
3. my bust. ok, this is going to sound weird, but i come from a long line of 'well endowed' ladies... hehehe. no implants or push-up bras here!

I'm not like a DD or anything, but my bust compliments my frame very well
