It's hard not to constantly picture Lily James as Cinderella since she starred in this year's Kenneth Branagh production, so we were surprised to see her in something more dark and grown-up looking than the frothy blue ballgown she wore for the title role. This embellished Alexander McQueen look, which she wore to the BBC War & Peace TV series photocall in London this week, is the perfect amount of sophisticated glam to signal her on-the-rise star power. We'll be watching this one closely in 2016, both on screen and on the red carpet. #SlayedIt! Slay or nay? Tell us on or , or in the comments below.
