Emma Watson Is A Dream In White At The Noah London Premiere

Emma Watson's red carpet style during her recent promotional tour of Noah has been pretty flawless. However, the British star saved her best dress for the London premiere of the film at the Odeon Leicester Square on Monday night.

Watson got heads turning in an all-white backless gown by Ralph Lauren. How did it look? Simple, elegant and definitely not bridal.

The actress paired her halter-neck style dress with minimal accessories - just silver cuffs from Jennifer Fisher, Monica Vinader rings and a matching metallic clutch were all she needed.

Watson's hair was swept up into a bun with a few sparkly pins and her makeup was subtle rather than statement-making (what does she do with all those beauty products?)

Co-stars Jennifer Connelly and Russell Crowe also joined Watson in London for the event. And can we take a moment to admire Connelly's beautiful Alexander McQueen gown?

The black organza design with floral detailing looked incredible on the actress. A well chosen contrast to Emma's white style too.

As for Crowe, he just looked chuffed to be standing in between the two leading ladies...
