The Easy A actress worked two trends in one for the occasion, clashing her prints perfectly while sticking to a sophisticated monochrome colour palette.
Stunning Emma oozed effortless chic as she took to the red carpet, sporting a black and white striped knit covered in sequins featuring a round neck and a slightly cropped design.
The starlet also wore a high-waisted, floaty skirt by Michael Kors, which featured a sheer tulle overlay boasting a white polka dot design. Cute!
With so much going on in her outfit Emma kept her accessories simple, teetering along in pointed patent courts (Louboutins, of course!) paired with dainty silver rings and tiny stud earrings.
She did, however, add a flourish of colour with her choice of lipstick, slicking on a vibrant raspberry pink hue to complement her porcelain complexion.
Emma was joined at the lunch by her fellow Oscar nominees including Bradley Cooper, Eddie Redmayne, Reese Witherspoon and Rosamund Pike.
The ceremony takes place in LA on 22 February, and Emma is nominated for Best Supporting Actress for her role as Sam in Birdman, in which she stars alongside Michael Keaton.
