This is a strange take. Western ideas of slim is from the 60s and no earlier. A lot of determined by fashion, with models looking better to showcase clothes being as slim as possible. Yet when talk about clothes off- such as playboy etc- it is apparent that wider hips and larger breasts arr the vogue.

One could argue then that women prefer slimmer women as an ideal, but men prefer women with those child bearing hips and breasts to hang onto.

As for me, I like big butts and I cannot lie..
