On Tuesday Krysten Ritter was a guest on the ‘Late Show with David Letterman’.

The actress opted to wear a flirty Z Spoke by Zac Posen Spring 2012 dress.

Her ink-blue silk jersey cold-shoulder dress with ruched detailing and a floaty skirt it the perfect look to match her fun personality.

Krysten styled her dress with Jimmy Choo strappy sandals with Swarovski crystals embellishments

H. Stern jewels, a high bun and a sultry red lip colour completed her look.
