The actress and director became the laureate of the "Drama 2022" award for her second directorial film "Don't worry, dear".
The film starred her ex-lover Harry Styles and actress Florence Pugh.
The 38-year-old star shone in front of the photographers' cameras in a very revealing black translucent lace dress by Christian Dior.
The dress had a plunging neckline and thin straps, Olivia's slender waist was accentuated by a wide belt, and the lace maxi skirt had a small train.
Olivia sported wavy hair and pretty rich makeup, and her nails were painted with translucent nail polish.
The star posed in front of the cameras with a golden statuette in her hands.
