The Cannes Film Festival is stepping up its red carpet rules for 2025 — and they’re making a bold statement: no nudity and no extra-large outfits.

Ahead of this year’s edition, festival organizers have updated the official dress code. According to their latest charter, nudity of any kind is strictly banned, not just on the red carpet, but throughout the entire festival area. Also on the no-go list? “Voluminous” dresses, especially those with long trains that slow down foot traffic or block seats in the theater.

“The festival welcoming teams will be obligated to prohibit red carpet access to anyone not respecting these rules,” reads the updated guidelines.

A rep for the festival confirmed to The Hollywood Reporter that these aren’t necessarily new rules — just ones that are now clearly written down. The focus, they say, is not to dictate fashion, but to ensure that full nudity is avoided, staying within French law and the festival’s traditional standards.

Over the years, Cannes has seen its fair share of sheer, skin-baring red carpet moments — think Elle Fanning, Bella Hadid, and Kendall Jenner. In 2022, a topless woman made headlines when she stripped on the carpet in protest of the war in Ukraine. While it’s unclear if a single event sparked the update, recent stunts — like Bianca Censori’s see-through Grammys dress — may have added pressure for change.

And it’s not just about what isn’t allowed — Cannes also continues to maintain strict black-tie dress code rules for major screenings at the Grand Théâtre Lumière. That means tuxedos and gowns are still the norm from 7 to 10 p.m., with formal wear like black suits, cocktail dresses, or even a little black dress all acceptable. But leave your backpacks and tote bags at home — those are banned too.

If this all sounds a bit too serious, remember Cannes has always been firm about appearances. In 2015, the festival faced backlash when women were reportedly turned away for not wearing heels. (That sparked plenty of criticism — even Emily Blunt called it “very disappointing.”) The rule was later relaxed, and stars like Kristen Stewart and Julia Roberts famously walked the steps barefoot in protest.

Over time, Cannes has also outlawed selfies on the red carpet and has always acted quickly to remove protestors or attention-seekers trying to disrupt the event.

This year, the new dress code fits right in with those past efforts to protect the festival’s polished image. But it leaves fans wondering: Will the rules apply to everyone, even A-list celebs? Brands like Chopard, L’Oreal, and Kering often send ambassadors down the carpet in dramatic looks, and it wouldn’t be shocking if they get some leeway.

Either way, all eyes will be on the red carpet from May 13 to May 24, as the 2025 Cannes Film Festival kicks off — and we’ll see just how well the new rules are followed.
