I think the issue about her balancing her weight could go eitherway honestly, it's true that if she's tilting her hips to a side she should compensate with her torso, but that does not necesarily mean her chest should turn the same direction her hips are.
Personally I honestly think that bringing a tit in there would sort of break the flow of the sprite. Since her posture already makes the butt stick out and on top of that the flowing robe also brings a lot more attention to it, it just becomes more natural for the piece to bring in the bootay
