Which body shape will be in "fashion" next?

We have had the soft skinned pale burlesque’s, the twiggy’s followed by the androgynous. Then it was the athletic (big shoulders slanting down to thin hips). The heroine chick, and finally the most irritating of all the “gym bunny”. I have probably left out a few, but when will the gym bunny die out. I am tired of their arrogant muscular bodies pontificating all over the place. What possibly could be the “new body shape” of fashion? I also think Madonna’s arms suck by the way.
