But not all waist to hip ratios would be considered curvy. The Barbie doll converted to real life do not have a significant waist to hip ratio. But I know plenty girls at university that would fit small but still extremely curvy.
Some women just are naturally curvy and some are just big and saying a woman isn't curvy just because she in a lower weight range is not fair to them either women of all body sizes can be curvy but i feel some bigger women try to use that description to get away from the fact that they are just over weight
An example All of these women are curvy but have different body types weight wise and/or all different heights but all are still curvy.
