Get the Look: Olivia Wilde black & white dress - 'LIVE! with Kelly & Michael'

Also, it's worth noting that another guest was new U.S. Open Men's Singles CHAMPION Andy Murray! How exciting was the final against Novak Djokovic last night? I know we talk fashion here, but I'm a huge tennis fan, and have been rooting for Andy to win his first major for YEARS! OK, I'll get back to fashion now...

Olivia's style has always been interesting - from major red carpet dresses (who can forget that divine brown strapless sequined gown by Marchesa at the 2011 Golden Globe Awards?), to her talk show appearances, which are easy, stylish, and never over-fussed. Today she wore - what looks like - Stella McCartney's signature black & white contoured dress. I say "looks like" as it would have been modified - and if it's NOT Stella's dress, check out the dress below for a nearly spot-on "Get the Look".. online at Net-A-Porter and Neiman Marcus.

Black and white continues to be a very popular trend - you can invest in some key dresses, but don't forget it's easy to mix and match what you already have in your closet!
