You should never be surprised to see the 27-year-old looking amazing in some of the latest and greatest pieces from the fashion house, because if Keira has a press tour coming up — or even if she’s just out for a night on the town — she’s never far from pieces straight off the runway of one of her favorite designer labels.

Last night, Keira was a guest on “Late Night with Jimmy Fallon” and dazzled her way to her chair in a beautiful black silk chiffon dress from the Fall 2012 collection, which was embroidered with brilliant 3D chain elements.

There’s a form of elegance and grace with a touch of ‘girl-next-door’ that Keira promotes, and I think that’s why I always find Valentino dresses so refreshing on her, despite how mature the cut or design may seem on the model — or anyone else.

Keira looked beautiful. She finished off her look with black pumps and smoky eyes.
