The one on the left has a good body fat percent for a woman - a bit of softness without looking jiggly. The problem is she obviously has fat friends and is spending her skinny years being a fat apologist when she should be shitlording and trying to maintain her figure, maybe even gain a bit of muscle mass. If she keeps up her current attitude, she will look like the chick on the right very, very soon (if she doesn't already).
