Shine bright like Bulgari!

Hollywood's hottest stars attended the Bulgari Decades of Glamour Oscar party on Feb. 25 at Soho House in West Hollywood -- and if it's any precursor to what we'll see on the Oscars red carpet this Sunday, we're in for a sexy, chic night.

QUIZ: Who's your red-carpet style personality? Find out!

As the event's host, Naomi Watts looked elegant in an Altuzarra gown with pink and red accents. The four-time Oscar nominee accessorized her look with a black clutch and vintage gold, amethyst, emerald, and diamond choker by Bulgari (naturally).

Kate Hudson had a modern take on the formal dress code with a yellow silk blouse and white leather skirt combo by Emilio Pucci with jewels by Bulgari. Goldie Hawn's glam daughter swept her hair into a breezy top knot and kept her makeup simple and fresh.

Emmy Rossum pulled out all the glam stops wearing a sexy sapphire wrap-style J. Mendel dress with a deep v-neckline. The Shameless star carried a Bulgari clutch and styled her hair in retro waves (with major shine!).

Olivia Munn looked ladylike in a cream-and-pink Bibhu Mohapatra dress with satin taupe Casadei pumps. The Newsroom actress styled her sleek hair with a side part and added a touch of drama with a berry lip.

Camilla Belle wore an intricate Prabal Gurung dress with a draped shoulder and Miu Miu pumps. However, her makeup upped the wow-factor: Dewy skin + orange lips + bold brows = Perfection.
