We'd follow Jennifer Lawrence's lead when it comes to most things, but particularly if we wanted to look this cool at any of our upcoming holiday cocktail parties. For her appearance on Late Show with David Letterman, the Catching Fire star traded jaw-dropping red carpet fare for a sophisticated-cum-edgy look that's a lot easier (and not quite as revealing) to outfit on our own. Just start with a sleek black pencil skirt and a lacy black top - a leather biker jacket will supply the edge, no chopped haircut necessary. As for the rest, you'll want to keep it simple: elegant black and white heels won't compete with the rest of the outfit, and a pair of geometric earrings will add just enough spunk. Shop your way to the coolest look in the room with our editors' picks below.
