Jennifer Lawrence traded out her brilliant red ball gown for classic black on The Late Show With David Letterman. The Hunger Games star has been wearing tons of black for her red-carpet cameos, and we love how she styled up basics to create a chic ensemble. For instance, a black trench coat will get a lot of mileage in your wardrobe and can be used for both warmth and style! While you can't really go wrong with black, we'd love to see Jennifer reach for something a little brighter at the SAGs and Oscars. Watch today's episode for the entire story.
