What a difference a few hours make!

We caught up with Olivia Wilde dressed in an adorable 1940s-inspired polka-dot dress and Prada shades as she ran a few errands, before making a quick change into some MC Hammer-style pants and a straw fedora hat for lunch at Little Dom's Deli in Los Feliz, on Sunday.

The actress has been busy promoting her new film, In Time, costarring Justin Timberlake and Amanda Seyfried, and she also recently filmed a documentary about the lives of women who work in Kenya's most impoverished areas.

Now that Wide has made her final exit from the hit series House, where her career first began, she's ready to officially kiss the small screen goodbye.

Check out our video of Olivia below, and tell us which one of her looks you prefer!
