Riley Keough wore a fully sheer Chanel Spring 2026 Haute Couture ensemble to the Histoires Parallèles premiere at the Cannes Film Festival on May 14, 2026, testing the festival’s two-year-old ban on nudity and transparent dressing. The look — a taupe organza blazer, top, and matching skirt embellished with charms, pearls, and bird motifs — technically complied with the rule because Keough wore a beige bra and short set underneath. The Chanel brand ambassador, styled by Jamie Mizrahi, became one of the most-photographed arrivals on the second night of the 79th Cannes Film Festival red carpet.
The Chanel Spring 2026 Haute Couture Look: Full Details
Keough’s three-piece Chanel ensemble was drawn from the house’s Spring 2026 Haute Couture collection, Matthieu Blazy’s debut couture season as creative director. The taupe organza blazer was cut soft and slightly oversized, layered over a matching sheer top and a column skirt grazing the floor.
Embellishments included scattered charms, freshwater pearls, beaded drops, and the bird motifs that ran through Blazy’s couture debut. Keough finished the look with Chanel’s signature two-tone ankle-strap pointed-toe pumps — nude leather with a black toe cap — and accessorized with pieces from Chanel High Jewelry. Mizrahi, Keough’s longtime stylist, kept hair and makeup deliberately low-key, letting the transparency carry the look.
Cannes’ No-Nudity Rule: What the Festival Actually Bans
Cannes introduced its dress code in 2025 after viral sheer moments from Bella Hadid and Naomi Campbell at the 2024 edition. The festival’s official language reads: “For decency reasons, nudity is prohibited on the Red Carpet, as well as in any other area of the Festival.”
The rule also restricts excessively voluminous outfits and dramatic trains that disrupt theater traffic flow and seating. Festival welcoming teams are authorized to deny red carpet access to anyone in violation. The 2026 edition marks the second year the policy is in force.
Enforcement has been inconsistent. Several high-profile attendees have tested the boundaries since the rule took effect — including Amal Clooney in a floor-sweeping Christian Dior gown, Julia Garner, and Alessandra Ambrosio, all of whom walked the carpet in looks that arguably brushed against the restrictions on transparency or train length.
How Keough Navigated the Dress Code
By layering a beige bra and short set under the transparent ensemble, Keough remained technically compliant. Fashion critic Catherine Kallon, writing for Red Carpet Fashion Awards, called the result a calibrated balance.
“Soft transparency, delicate embellishment, and muted palette all work in harmony with her naturally low-key presence.” — Catherine Kallon, Red Carpet Fashion Awards
The look lands in a sweet spot — covered enough to clear the rule, sheer enough to dominate the night’s coverage. It follows a season of celebrities pushing the limits of what counts as compliance, joining a wave of daring red carpet looks in 2026 that test the festival’s enforcement appetite.
Keough on Matthieu Blazy’s New Chanel Direction
Keough has been a Chanel brand ambassador since 2023, putting her at the center of the house’s transition into the Blazy era. Speaking to WWD on the red carpet, she described the gown in unusually direct terms.
“It was just one of the most beautiful things I’ve ever seen in my life.” — Riley Keough on her Chanel look
On Blazy’s broader creative direction, Keough added: “It’s like a whole new era, and just so like modern in a sense, but so sort of classically Chanel as well. It’s kind of genius.” Blazy joined Chanel as creative director in 2025 after his run at Bottega Veneta. The Spring 2026 Haute Couture is among his first full collections for the house, following Matthieu Blazy’s Chanel Cruise 2027 show in Biarritz and ahead of Chanel Métiers d’Art 2027 in Rome later this year.
Keough is at Cannes 2026 to promote Butterfly Jam, director Kantemir Balagov’s English-language debut, which opened the Directors’ Fortnight sidebar. Other Chanel ambassadors have also driven major moments this season, including Anne Hathaway in Chanel and Chanel’s Met Gala 2026 moment.
