Stars channeled their dark sides for the Vivienne Westwood U.S. Flagship Store Grand Opening.

Some of the more notable looks of the evening included those of guest of honor Christina Hendricks (who kept it somewhat casual in a corseted, off-the-shoulder top and cropped pants), Dita Von Teese (who stole the spotlight in a quintessentially Vivienne Westwood gown and feathered headpiece) and Malin Akerman (who worked it in a graphic Vivienne Westwood sheath and metallic peep-toes).

Mischa Barton (who looked surprisingly chic in a silver, toga-style tunic and sandals) and Kristin Davis (who kept it classic in a pool-blue, asymmetrical cocktail dress) were also on the scene.
