Heidi Klum has traded costumes for corsets.

The supermodel, 52, landed at the Cannes Film Festival 2026 this week with a wardrobe full of cinched, snatched and sparkling gowns.

Her latest? A chocolate brown lingerie-inspired satin dress with sheer side panels, underwire cups and a ruched high-slit skirt, worn to the Kilian Paris Beach Club after-party on Tuesday.

The evening doubled as date night with her husband, Tokio Hotel guitarist Tom Kaulitz, 36, who got festive in a sheer animal print shirt.

A red carpet regular on the Riviera, Klum kicked off her week at the opening ceremony in a pale peach Elie Saab gown with a corseted bodice, plunging neckline and a pink floral accent at the center of the décolletage. She accessorized with Rene Caovilla sandals.

For dinner that night, she slipped into a gold Naeem Khan fringed beaded cocktail dress, keeping the metallic theme going with coordinating heels and a gold Aigner evening bag.

By Thursday, Klum was on duty for her role as a Magnum ambassador, closing the ice cream brand’s inaugural House of Magnum runway presentation in a glittering pistachio green strapless gown by Raissa Vanessa.

For the after-party, she traded pistachio for chocolate in a brown Sophie Couture gown with a glossy corset bodice, exaggerated hips and a long fringed skirt. The lacquered finish and cracked overlay were designed as an homage to Magnum’s chocolate shell.

Her son, model Henry Samuel, 20, walked in the Magnum runway show and posed for photographers alongside Klum. Samuel, whom Klum shares with ex-husband Seal, has been a frequent fixture by her side throughout the festival.

He also joined her Monday for the “Fjord” premiere, where stylists Mariel Haenn and Rob Zangardi put Klum in a custom Monique Lhuillier two-piece: a corset and matching skirt in gold hand-embroidered lace, styled with a white taffeta opera coat with voluminous sleeves and a train that pushed the boundaries of the festival’s strict dress code.

The rules prohibit “voluminous outfits, in particular those with a large train, that hinder the proper flow of traffic of guests and complicate seating in the theater” — but Klum has been known to skirt the guidelines.

A L’Oréal Paris and Magnum ambassador, Klum has been busy with events for both brands between red carpet appearances — and with the 79th Cannes Film Festival running through Saturday, her corset collection may not be tapped out yet.
