Each gorgeous star played up their signature style in designer gowns fit for the high-profile event at the Palais des Festivals. The ever-elegant Naomi Watts looked radiant in a dusty blue Marchesa gown with black diamond crystal embroidery at the waist and neckline. Watts, the face of Bulgari, accessorized with a diamond serpent necklace and offset the shawl sleeves with side-swept curls.
Cate Blanchett, a long-standing style crush at Us Weekly, shone bright in a Givenchy gown. The bodice featured elaborate multi-colored embroidery on the front and a sheer-illusion back. She added even more glitz with sapphire Chopard earrings. Blanchett's blonde bob was pulled into a low chignon with side braids adding texture.
While America Ferrera tends to lean conservative on red carpets, she chose a sexy cream princess gown by Georges Hobeika Couture that had a cleavage-revealing sheer panel down the middle of the bodice. Her voluminous hair was pulled into a messy ponytail, and she opted for a bright red lip for a pop of color.
