The metallic gold, the embroidery and the classic cut all work to make Knightley stand out from the drab rainy evening, and who better to have on your arm than a man whose style has been commended by the hard-to-please Anna Wintour.

Keeping her make-up minimal, and her hair natural and wavy, Knightley offsets the drama of the dress perfectly and the statement earrings finish things off to perfection.

Even with umbrella in hand, this pair are a vision.
