Kristin Cavallari often impresses us with her sleek style, but the latest black and white colorblock Alice + Olivia dress that she wore to the 2012 FFANY shoes on sale gala in NYC makes us want one too, pronto! Colorblocking is huge right now and we particularly love the slick mix of black and white. Can it get any chicer than two chic colors colliding? We think not. The new mom finished her red-carpet look with these Chinese Laundry black platform pumps ($130) and sparkly drop earrings. To get Kristin's look for your next fancy event, or even for a dinner date, shop our favorite black and white colorblock dresses below, including this Milly colorblock leather dress ($395), which is very similar to Kristin's.
