Stars Turn Out in Dramatic Gowns at 79th Cannes Film Festival

Sequins sparkled, trains swept the red carpet and diamonds flashed as celebrities arrived for the 79th Cannes Film Festival in France.

Demi Moore wore several striking outfits. One was a red gown with oversized sculptural shoulders and a body-hugging silhouette, paired with diamond earrings and a bracelet. She also appeared in a lavender off-the-shoulder gown made of sheer, shimmering fabric that featured a flowing train and thigh-high slit. At another event she wore a white sequined mermaid gown with a sculpted peplum waist and a large diamond necklace.

Heidi Klum stepped out in a peach-draped gown with floral embellishments and soft gathered detailing that ended in a sweeping train.

Riley Keough chose a strapless black gown with an oversized sculptural skirt and a high slit. Andie MacDowell wore a flowing sleeveless black gown with sheer paneling and subtle neckline cutouts.

John Travolta paired a dark three-piece suit with a cream tie, round glasses and a cream beret. Cara Delevingne wore a dark pinstriped pantsuit over a sheer blouse.

Dylan Sprouse and Barbara Palvin appeared together, with Palvin showing her baby bump in a pale blue feather-trimmed maternity gown while Sprouse wore a black tuxedo. The next day Palvin changed into a crisp white blouse tucked into a dramatic black floor-length skirt with an extended train.

Diane Kruger wore a pale floral mini dress with a dark green cape-like scarf and a braided up-do. Jane Fonda and Julia Louis-Dreyfus both chose black sequined gowns with sleeves and high necklines.

James Franco climbed the stairs in a black tuxedo and bow tie with dark sunglasses. Vin Diesel arrived with the Fast & Furious cast. Michelle Rodriguez wore a silver corset gown, and Meadow Walker, Paul Walker's daughter, wore a neon lime-green asymmetrical dress. The men in the group wore classic black tuxedos and tailored suits.

Joan Collins wore an architectural white gown with sculptural ruffles around the shoulders and bodice, long black gloves, sparkling jewels and silver pointed heels.
