Emma Watson was spotted outside David Letterman's studio in NYC wearing a chic black-and-white ensemble that's super easy to re-create, and you probably already have the main pieces in your closet. The actress started with a black tank and black J Brand cropped jeans ($297), then topped it off with a crisp white blazer. For extra pizazz, Emma finished her look with black-and-gold chain-strap Tom Ford sandals and a gold necklace. What's great about this outfit is that it can work everywhere from the office to a party to a day of running errands. While Emma's exact sandals aren't available online, shop these similar BCBGMAXAZRIA chain sandals ($195) for the same edgy effect. Swap the heels for these Dolce Vita flat chain sandals ($169) if you seek a comfier alternative.
