Riley Keough put the Cannes Film Festival's no nudity rules to the test when she rocked up in a sheer outfit on Thursday evening.
The 36-year-old defied the festival's "explicit" dress code, which was enforced last year, which bans several types of gowns, particularly the celebrity-favored 'naked' dress, defined by barely-there materials, such as sheer mesh, tulle, lace, or crystals, that create the illusion of nudity.
Riley seemingly ignored the rules and arrived on the red carpet at the Histoires Parallèles (Parallel Tales) premiere in a sheer, blush organza two-piece from Chanel's 2026 spring collection.
The actress looked gorgeous in her rule-breaking set, which featured a loose shirt and a matching skirt, both with embellished trimmings, that exposed her lingerie underneath.
In 2025, the Cannes Film Festival announced "explicit" dress code rules for stars to follow, prohibiting nudity and voluminous outfits.

"The aim is not to regulate attire per se, but to prohibit full nudity on the red carpet, in accordance with the institutional framework of the event and French law."

"Voluminous outfits, in particular those with a large train, that hinder the proper flow of traffic of guests and complicate seating in the theatre are not permitted."

The Cannes Film Festival has stuck by its dress code this year and even offered up some style guidelines for guests attending screenings.
"For the Grand Théâtre Lumière gala screenings taking place around 7 and 10 p.m., which are attended by the artistic teams, evening wear (long dress, tuxedo) is required," it states on the festival's FAQ page.

It adds that "tote-bags, backpacks or large bags are prohibited during gala screenings."
In 2015, the BBC reported that Cannes was "turning away women in flat shoes" from its premieres.

Riley isn't the first star to break the new dress code rules. Last year, Amal Clooney wore a Christian Dior gown by John Galliano, which had a prohibited floor-sweeping train, and Julia Garner and Alessandra Ambrosio both wore dresses featuring sheer materials and flowing trains.
