A woman with large breasts and a small waist. It's what all men want, isn't it? Western men are often cited as -- or accused of -- being obsessed with the large breasts/small waist ideal. It objectifies women, some women say.

That may be, but research has confirmed that Western men prefer this body shape. (It's my guess, judging from the extreme manifestation of the same body shape type in manga, that Japanese men share that preference, but that's another story.)

The question is, do men prefer the hourglass, Barbie body shape for cultural reasons (whatever they are) or is there an evolutionary basis for the preference?
