The actress, who is hotly tipped to receive her 17th Academy award nomination later this month for her portrayal of former British Prime Minister Margaret Thatcher, looked stunning as she posed for photographers at the event.
We love the cut of her dress and the statement gold ring and clutch. The chunky youthful ankle boots were a fun touch too.
Also in attendance was French screen legend Catherine Deneuve, who looked every bit as classy.
