Emma Stone wore a fresh-off-the-runway Lanvin gown - pink & red are one of the hottest trends of this season and she wore her gown well!
Amy Adams went for a peach coloured Elie Saab dress, I think the colour looks lovely with her hair.Emma Watson's Valentino gown was a little colourless and her slouchy pose made it look worse; her makeup is spot on though.
