Dutch model Doutzen Kroes, who turned 30 this year, looked incredible in her daring cut-out Atelier Versace gown with thigh-high split.
Attending the event with her husband, DJ Sunnery James, the mother-of-two teamed her gown with silver Chopard jewelry and Jimmy Choo sandals.
Looking every inch an angel, 22-year-old Karlie Kloss donned a shimmering silver and white Atelier Versace Couture jumpsuit from their Autumn 2014 collection.
Karlie accessories her outfit with Versace custom silver pumps De Grisogono jewels and makeup by L'Oréal (for which she recently became an official spokesperson).
Catwalk queen Bar Refaeli also opted for white, pairing this draped white design with De Grisogono diamond drop earrings and a simple cream clutch.
