Olivia Wilde in Talbot Runhof at Revlon ColorSilk Launch

It’s Fashion Week! And Olivia Wilde’s hosting duties at the Revlon Luxurious ColorSilk Buttercream launch held at The Royalton Hotel on Feb. 7 in NYC coincided with the start of 2013 New York Fashion Week.

Here she is looking lovely in a Talbot Runhof dress, Nicholas Kirkwood heels, and Iwona Ludyga jewelry.

By the way, the mega-star is engaged to “Saturday Night Live” alum Jason Sudeikis, and the duo recently performed together in a show called “Gravid Water” at New York’s Upright Citizen’s Brigade Theater.
