Cate Blanchett In Ralph Lauren -  The Royal Marsden DinnerCate Blanchett was also among the stars on the dinner-party guest list at the Duke of Cambridge’s The Royal Marsden Dinner, hosted at Windsor Castle in England on Tuesday (May 13), where she joined Zhang Ziyi, Margot Robbie and Emma Watson.

As is custom, Cate was the epitome of elegance in a white Ralph Lauren Fall 2014 one-shoulder column gown.

The classic-contemporary design was only made sleeker with the half-cape detail that draped over her arm.

Of course, the look was impeccable styled with crystal chandelier earrings, a refined cream clutch, radiant makeup and a side-swept updo.

J’adore.
