Like I said she lacks elegant features

Snow White and Jasmine are more graceful than her.

I am a bit torn on this as I think Jasmine is quite graceful and elegant but she hunches a lot whenever she sits so her posture is not so great.

That being said, Tiana is always working so her posture isn't the best either, but she looks pretty graceful working back to back shifts.

^i agree. First i was of opinion that Snow's childishness comes in between her womanly elegance, making her giggle or react in awkward ways, but then i realized Jasmine as a person is very grouchy, which makes her less graceful.

Out of them definitely her. She is just too young to be graceful. Jas and Tia are both very graceful even thought Tia is a frog most of the time in her movie.
