Sienna Miller Stunned in Glamorous Gown during the Closing Ceremony of Cannes 2015

From her casual chic ensemble when she first arrived at Cannes, to her simple column dress in Calvin Klein's event, and to her unforgettable red carpet gowns, Sienna Miller is ending her red carpet run on the 68th Cannes Film Festival in style. 

Sienna wore a beautiful cerulean blue Gucci gown at the premiere for Le Glace Et Le Ciel (Ice and Sky) and the official closing ceremony of the festival.

The leather and lace was a daring combination, but the 33-year-old fashionista pulled it off effortlessly well.

While the top part was just a simple plain top that fitted her like a glove and showed off a peek of her cleavage, the bottom part was a full layered lace skirt that dramatically flows as she walked and posed on the red carpet.

The gown also featured a long ethereal train, which was the epitome of a princess dress.

She added a nude-color applique belt to cinch her waist and break the monochromatic look. She accessorized with a pair of simple drop earrings that matches the color of her belt.

The British beauty wore barely-there makeup, soft smoky eyes, well-defined brows and a nude pout. She styled her blonde bob in a wavy textured hairdo, with her fringe twisted in two parts and pinned off her face.

She served as a jury for the festival this year along with actor Jake Gyllenhaal and several other film industry insiders and influencers.

Before that she was also spotted in another Gucci gown at the screening of Macbeth. The dusty brown Gucci dress had beautiful tiered ruffles and a red bow with a high neckline and ruffled shoulders.

Sienna Miller made her mark at this year's Cannes Festival, night after night she wowed everyone in show-stopping gowns and pulling off difficult outfits imaginable.
