Olivia has always laid claim to a certain girl-next-door quality, but the sultry Michael Kors creation she wore for her appearance on the Late Show with David Letterman in New York City on Tuesday was far from innocent. Her Pre-Fall 2013 strapless dress included a banded bustier top and a sleek lace-accented skirt. The Newsroom actress completed the unexpected look with a pair of nude Christian Louboutin So Kate pumps.We like the fact that Olivia's shaking things up a bit in the style department, but don't really like the black seaming detail on the top half of her dress. What are your thoughts on the star's talk show ensemble?
