On the red carpet: Emma Watson

Emma Watson was breathtaking in a Ralph Lauren white silk halterneck dress at the London premiere of Noah.

A sophisticated look, and the thigh-high slit gave it a raw edge.

Emma Thompson just gets better and better. She was stunning in a white, figure-hugging Maria Grachvogel dress at the Empire Film Awards. Stark, simple styling completes a perfect look.

Kate Garraway shows how not to wear a jumpsuit at the premiere of I Can’t Sing. Her blunt fringe and tuxedo jacket hit every trend note — but the baggy and ill-fitting catsuit is a style disaster.

It was always going to be hard to compete with the stark simplicity of Emma Watson on the Noah red carpet, as Jennifer Connelly proves in an over-elaborate dress by Alexander McQueen.
