The great and the glamorous descended on the Barker Hanger in Santa Monica on Thursday night for the 2014 Critics' Choice Movie Awards - and Margot completely and utterly stole the show (and our hearts) in a stunning jumpsuit with a sheer black lace back.
Margot wowed in the Elie Saab jumpsuit, which she paired with Christian Louboutin shoes, Alexander McQueen bag, and Ilena Makri jewels.
Her makeup was fresh, subtle and youthful, and her blonde hair tousled and voluminous.
A cool smattering of rings added further edge to the look, which was one of our favourites from the night.
Margot and her fellow castmates were up for the Best Acting Ensemble Award but lost out to American Hustle.
