Margot Robbie In Ralph Lauren - The Royal Marsden DinnerMargot Robbie was also at the dinner to celebrate the work of The Royal Marsden, hosted by the Duke of Cambridge at Windsor Castle in England on Tuesday (May 13).

Like Zhang Ziyi, Margot worked several shades of grey, hers also courtesy of Ralph Lauren’s Fall 2014 collection.

The long-sleeve, jersey-style wrapped bodice with an open back provided a casual contrast to the slinky silken skirt that languidly puddled on the ground.

She accessorized with gemstone pendant earrings and a matching clutch, but it was her heavy kohl-rimmed eyes that proved an unnecessary distraction here. A lighter touch would have been preferred.

Last week didn’t bring Margot’s greatest style moments. Has her grey gown put her back in your good graces?
