Red leather is undeniably cool, and we can't think of a better time than NYE to bust out festive red leather shorts à la Ashlee Simpson. Aside from her bold bottoms, we love that the singer opted to soften her look with a silky white button-down blouse. Black booties, a black clutch, and a few gold jewels — including this exact Jennifer Zeuner arrow necklace ($143) — completed Ashlee's outfit. If it's too cold to go bare-legged, we recommend throwing on some black tights, too. And don't forget a chic black coat for extra warmth!
