Most recently, Kylie led the charge on "butt cleavage"—a booty-baring craze coined by Cosmopolitan. By slashing her jeans on the lower portion of each cheek, Kylie produced what the mag describes as "like underboob but underbutt."
Now is everyone flashing butt cleavage à la Kylizzle? No, not yet, at least, but the 19-year-old style icon often leads the charge on things like this. Give it a few weeks, and there's a good chance you'll be seeing more of this booty-baring fashion on Instagram and maybe even IRL.
