I've noticed that, the skinny youngster with big fat hooters. I'm thinking bra help is a big factor, though some may be implanted. I had a roommate who was a little 5'3" 90 pounder and she was all boobs. Hers sagged mightily at 20. Certain industrial strength shape and form bras would give her a more rounded shape up top.

I lost in the ass lottery, dammit. I always had a flat ass up until about the past year. I'd love an ass that sticks out! As well as hips. I have absolutely none!! Ah well... I guess the boobage makes up I think...
