The Gravity actress went for a colourful, summery look in a pretty leaf print dress designed by Peter Pilotto, which featured a jagged hemline.
Sandra, 49, paired her cheerful number with a pair of lime green courts by high street fave Kurt Geiger, adding a navy clutch which tied in with the blue details on her dress.
The mother-of-one let her bright outfit do all the talking by ditching the jewellery and styling her brunette locks in low-key tousled waves.
To complete her look Sandra opted for natural hues of make-up, highlighting her chocolate peepers with brown smoky eyeshadow before slicking on a nude pout.
It's fair to say Sandra had a brilliant night at the star-studded bash, taking home gongs for Favourite Movie Actress and Favourite Dramatic Movie Actress thanks to her role in Gravity, as well as Favourite Comedic Movie Actress for her film The Heat.
She also won Favourite Movie Duo alongside her Gravity co-star George Clooney, with the film itself triumphing in the Favourite Dramatic Movie category.
