Would Carrie Bradshaw approve?
All that's missing is a beret and white gloves and she could have started miming down the red carpet!
But alas! She didn't, and opted for black Jean-Michel Cazabat pumps and Fred Leighton jewels instead.
It's certainly not her best look, and she probably could've benefited from some lipstick, but you have to hand it to her that even after all these years, she still causes a stir at these big events.
Rose Byrne shouldn't feel threatened, though. She holds the title for pulling off the best Elie Saab jumpsuit look of all time!
