Kaley Cuoco made a guest appearance on the ‘Late Show with David Letterman’ in New York City yesterday evening.

The actress was there to promote the season premiere of ‘The Big Bang Theory’, which airs this Thursday.

She wore a vibrant blue Collette Dinnigan Resort 2013 dress.

I would like to think she styled this silk dress with lace panels around neckline, waist and sleeves with nude pumps like the model in the look book picture.
