Another explanation I've heard is that size preference maps to when women are asserting themselves (ourselves?) socially. So you have suffrage in the 20s, and the demand for thin women. 2nd wave feminism in the late 60s-70s? Twiggy. And so on.
No one explanation is going to be sufficient, because we're too complicated for simple cause and effect, but this is one of the ones I find interesting...
