Week in Chic

Ingénue Carey Mulligan went on a whirlwind press tour to promote her new film, An Education in New York City. For an appearance on David Letterman, she took a monochromatic approach in head-to-toe Prada. At the Paris Theatre premiere, she once again chose Prada, paired with Fred Leighton jewelry. For the Cinema Society screening, Mulligan proved less is more in a Bottega Veneta dress.
