But men's obsession with shapely butts has remained strong ever since—and Kim Kardashian has the Instagram hits to prove it. In fact, you might say that rears have replaced breasts as our most scrutinized body part. But here's some interesting news: Research from the University of Texas at Austin found that what men are really drawn to isn't so much the size of the derriere, but the curve—or, more specifically, a spinal curvature that offers the illusion of a shapely butt.

What researchers found: Overwhelmingly, men preferred the uber-bendy images that showed the lower spine curved at a degree angle, from back to buttocks. Pretty interesting, but do things change when butt size comes into play? To find out, the researchers asked men to look at images of women with different butt sizes and spinal curves.
