Old hot. I think it's trending more towards recognizing it as malnutrition, these days. Kate Upton's about the size of the "new hot."
I'd take 2009 Christina Hendricks or Scarlet Johannson over Kate Upton... Kate's lower body is lacking curvature...
Possibly malnutrition. But very normal bone structure too. Well, maybe not as much in America where 50% are overweight. My wife has those sort of 'child bearing' hips and there is no malnutrition there.
