If you mean runway models I completely agree. Androgynous bordering on anorexic. But I think the VS models do have curves at least and are more athletic than anorexic.
So we blame the men ....again!
I agree in part, but boys get conditioning too. 'Boys don't cry' 'suck it up'. Not every boy gets to be captain of the football team or even on the team. But there seems less resentment by boys/men of the ones who do. It's a man's world though by and large, so that might explain it.
