The stunning starlet pulled out all the fashion stops for the bash, which celebrated individuals who have helped to raise awareness of the accessories industry.
We all know Olivia is a seasoned fashionista, so it's no surprise she bagged the Distinguished Style Award at the ceremony.
She hit all the right notes in a slinky black frock which featured draped fringing and sparkling shoulder embellishment.
The socialite was suitably equipped on the accessory front too, flaunting an unusual clutch by RAFE New York, a statement necklace and chunky gold arm swag.
Metallic strappy sandals showcased her deep burgundy pedi while her locks were swept back into a sleek low ponytail.
The former The City star was then joined by model boyfriend Johannes Huebl before heading to her second engagement of the night.
Olivia was all smiles as she posed with her handsome beau at the W Magazine cocktail party, sporting the same show-stopping frock.
She warded off the evening chills in a coat which featured caramel coloured knitted sleeves.
Meanwhile Johannes matched his girl in the style stakes, looking dapper in a velvet blazer teamed with a black bow tie. Cute!
