Actress Stana Katic at the 2010 Screen Actors Guild Awards on January 23.
To be honest I only noticed Stana because she had be incorrectly labeled Mischa Barton, and she does really resemble her from some angles - but I'm glad I did take notice as Stana looked superb in a grey sparkle covered Oday Shakar gown with drapey low-cut back and gorgeous Martin Katz earrings that looked a different color from every angle.
She also wore some unseen Sergio Rossi heels.
Edit - Just added designer info
