She manages to look soft without flab everywhere, which, to me, is the mark of an actual curvy person.
I'm pretty sure this is what most people mean when they say they prefer curvy women. Not that faux-curvy where you cover everything with fat in an attempt to imitate this body-type...
What a sexy girl!
While I definitely share your view on that this is what "curvy" actually looks like (soft without fat rolls or flab, and rounded breasts and hips despite being very slim), my experience tells me that at least in Latin countries (I'm from Mexico) there are a lot of people who like and in some cases prefer buxom women, as skinnies are considered by them to be "too scrawny" or not "womanly" enough because of their smaller frame.
Regarding Kelly, I think part of the reason why she looks slim but soft is because her exercise regime consists almost exclusively of cardio, she doesn't seem to do weights or resistance exercises of the kind that gives that ultra-fat free, ultra toned and defined muscular shape.
Although her abs are surely defined! damn...
