Emily Hughes isn't fat, but she does have what I would call 'thunder thighs' and her hips are, well, ample (without being fat). She is just what you might call bottom-heavy, not like most skaters who are pretty much up-and-down.

To me, "curvy" denotes a reasonably well-endowed bust (without overdoing it) and hips that nicely balance out the bust. I don't think any current skaters could be called curvy, and that includes Emily, who is rather flatchested.
