Cannes Fashion Highlights

Cannes Film Festival is about so much more than just movies. It's also one of the biggest celebrity events in the world - pulling in stars ranging from Marion Cotillard to Nicole Kidman, Lupita Nyong'o and Julianne Moore for 12 days of red carpet photocalls. Here were the 67th annual festival's greatest fashion looks:

MARION COTILLARD
Taking an edgy style risk, Cotillard wore a short Maison Martin Margiela couture dress made of bric-a-brac from a flea market for the "Two Days, One Night" screening. The gamble paid off beautifully. Cotillard's colorful minidress in silk organdy and pongee, which sported a turtleneck, was made up of screws, beads, buttons and bits of beer cans. It came from the fashion house's spring-summer 2014 collection and took a reported 67 hours to make. At the amfAR charity dinner, Cotillard also looked ethereal in an embellished off-white sleeveless gown with segmented panels by Alexander McQueen.

BERENICE BEJO
The raved-haired French actress looked elegant for Michel Hazanavicius' "The Search" premiere in Alexis Mabille's radiant black-velvet, double-breasted bustier gown. Although the dress was a sure-fire hit, the movie got mixed reviews.

Uma and Sophia

UMA THURMAN
Thurman wowed the crowd at Cannes' "Clouds of Sils Maria" premiere in a canary yellow custom-made Atelier Versace couture gown in silk cady and chiffon. A gathered waist and separate trains, which blew in the breeze, gave the gown a classical, timeless vibe - but the psychedelic color gave it an edgy lift. Thurman was in Cannes for the 20th anniversary celebration of "Pulp Fiction," which won the Palme D'Or in 1994.

SOPHIA LOREN
The svelte 79-year-old siren Loren outshone women half her age in head-to-toe red at the screening of "Human Voice," directed by her son, Edoardo Ponti. Loren, who was honored as a special guest at this year's festival, also wowed in an embellished champagne couture dress by Armani Prive for the premiere of "Two Days, One Night."

Cate, Jessica and Lupita - Oh, My!

CATE BLANCHETT

Academy Award-winner Blanchett broke the fashion mold with panache at the "How to Train Your Dragon 2" screening at Cannes, wearing a multi-colored, bejeweled bodice and a chic black pleated floor-length chiffon skirt, courtesy of Givenchy. While the Cannes red carpet relies mainly on ball gowns, Blanchett stayed ahead of the fashion pack by thinking outside the box. Her sapphire chandelier Chopard earrings added a touch of class.

JESSICA CHASTAIN

Ivory-skinned, red-haired beauty Chastain looked like an ethereal Roman goddess for the "Foxcatcher" premiere at Cannes in a gown by Elie Saab. The asymmetrical, one-shoulder, silk couture gown - in on-trend purple - fluttered as the French Riviera wind picked up, showing its delicate ruffles. Taken from the haute couture spring-summer 2014 collection, Lebanese designer Saab showed he's lost none of his talent with va-va-voom traffic stoppers.

LUPITA NYONG'O

Oscar-winning actress Nyong'o shone bright at the Calvin Klein Women in Film event in Cannes, wearing a shimmering blue Calvin Klein strapless dress with a slashed bodice. To complement the look, the "12 Years a Slave" star wore teardrop cutout crystal earrings and silver sandals.
