I'm more than happy to agree to disagree. 
I totally see it, and am bemused that others can't. Women come in all differrent shapes and sizes - tall, short, broad-shouldered, long-waisted, short-legged, athletic, big-bottomed, flat-bottomed, pronounced waist, no waist, strong-thighed, knobbly-kneed, and don't even get me started on the zillion different shapes breasts come in.
Yet, we're only ever presented with one, very narrow definition of how a woman should look and it's virtually unobtainable for the vast majority; almost certainly so for women who've had children.
So different from the situation for men. Men are men regardless of shape, regardless of age, regardless of parental status.
The Dove campaigns try their best to present different shapes and looks, but it's a drop in the ocean, and (possibly subconsciously) seen as almost too gimmicky (patronising?) by most people.
Again, humans aren't meant to be fat.
