US actresses including Leading Actress award winner Julianne Moore chose to wear British designers at tonight's Baftas.

Moore looked striking in a bright red Tom Ford gown, while fellow nominee Reese Witherspoon wore a low-cut purple dress by Stella McCartney.

Moore said: "I am wearing Tom Ford. Tom loves it here in London, and was nice enough to make me this wonderful dress, so it's a thrill to be able to wear it."

Meanwhile Witherspoon admitted she was finding her first Baftas colder than the Oscars and wore a coat over her shoulders to keep her warm.

She said of getting ready for award ceremonies: "It's fun, I enjoy it. I'm wearing Stella McCartney. I get to hang out with friends and have fun."

British nominees Keira Knightley and Felicity Jones both opted for floral detailing.

Knightley, rumoured to be expecting her first child with Klaxon husband James Righton, wore a black and white strapless frock by Giambattista Valli covered in individual flowers that disguised any hint of a baby bump.

Monochrome was a stand-out theme on the carpet. Rosamund Pike wore a floor-length halterneck dress by Roland Mouret, while Amy Adams stood out in a white number by Lanvin.
