For her third look, the Hathaway slipped into a Vivienne Westwood corseted gown layered with taffeta and lace smattered with sequins.
The princess-style gown was said to have been specially designed for the actress in London.
Setting off the grey tones, she paired the gown with a stunning diamond and dusty amethyst necklace from the Tiffany Archives.
The biggest risk for Hathaway came in her silver-tasselled Oscar de la Renta gown.
