I think Tiana is curvier and Pocahontas is more toned.

The dress really shows her hips, Pocahontas does too but even as a frog you could see Tiana's curves

This is a hard one

Not really sure....

A body can be curvy and toned.
Pocahontas has bigger bust and hipps and a tiny waist (an hourglass figure).
She has big boobs and a big butt.

Tiana is curvy as well, Pocahontas is just curvier.

I think

tiana looks a little emaciated

all but mulan are curvy... also belle ad tiana have the same figure so i dont really understand why these two were picked, but tiana has a smaller waist + bigger hips

^Snow White's not curvy either and Tiana definitely has a bigger butt and hips than Belle.

Not super sure..

Snow White is a bit curvy, just not as cartoonishly defined. You don't need big boobs to have a defined waist (aka curviness).

also, people: curvy is a NOT a size, skinny is NOT a shape, and for crying out loud, Pocahontas is way skinnier. But Tiana has the typical cartoon hourglass, so her waist is way tinier than Pocahontas' proportionately, which makes her curvier, though it's hard to say. But like she said, almost all are curvy, in different ways. it's how cartoon girls tend to be.
