She was left red-faced when her voluminous Dior gown caused her to trip up while making her way on stage to collect her Best Actress Oscar on Sunday night.

So when it came to choosing an outfit for the Vanity Fair post-Oscars event, winner Jennifer Lawrence opted for an outfit more suitable for celebrating in.

Jennifer swapped her pale pink red carpet dress for a slinkier silver plunging Calvin Klein number as she posed up with her award at the event, held at Sunset Tower in Los Angeles.

Naomi Watts opted to stay in the same vein as her earlier awards ensemble, keeping things metallic in a black and gold one-shouldered gown for the Vanity Fair party.
