Honestly, I think ethnicity comes into it a lot. Black girls like Nicki can really pull off curves but often white girls can't. It's just genetics. It'll go to their hips and thighs rather than their boobs and ass. Consequently I can't imagine any of my skinny, white girlfriends deciding to thicken up. They all seem to love being really skinny

Particularly in Australia where the beach culture and wearing bikinis are huge.
