First it was the bra straps that kept “accidentally” peeking out from under tank tops.Then in fashion tandem thongs and low-rise pants gained in popularity.

Reportedly a favorite of Charlize Theron, Rosanna Arquette, Daryl Hannah, and Jennifer Lopez, the clingy mix of denim and Lycra comes both in a 4 1/2-inch rise and a scandalously low 3-inch rise just enough to cover, well, not much. But, the sickest leather edition just hit Amy Chan in NoLIta, so at least parts of you can stay warm.
