The 79th [1] Cannes Film Festival has implemented a strict dress code banning skin-baring looks and sneakers at gala screenings this month [1].

These regulations represent a shift in how the world's most prestigious cinema event manages its public image. By restricting specific fashion choices, organizers aim to prevent disruptive red-carpet incidents and ensure a consistent level of formality at high-profile venues like the Grand Théâtre Lumière [1, 2].

Festival Director Thierry Frémaux and other organizers said the goal is to preserve a “timeless, elegant aesthetic” [1, 2]. The new rules specifically target attire that deviates from traditional formal wear. Banned items include sneakers and gowns with oversized trains, which have occasionally hindered the flow of traffic during gala arrivals [1, 2].

While some reports characterize the update as a “nudity ban” [3], other sources emphasize that the focus remains on maintaining formal standards, such as long dresses and tuxedos [2]. The restrictions apply specifically to the gala screenings, where the dress code has historically been the most rigid.

Reports of the updated guidelines first surfaced on May 13, 2026 [1]. The rules come as the festival seeks to balance the desire for modern fashion expression with the prestige of the event's heritage. There is some contradiction regarding the extent of the ban; while some sources suggest a broader restriction on certain types of evening wear [4], others clarify that the ban is limited to specific elements like excessive trains and revealing cuts [1].

Organizers have not provided a list of specific penalties for guests who violate the code, but the guidelines serve as a formal directive for attendees and their stylists preparing for the event in France [1, 2].

“The goal is to preserve a “timeless, elegant aesthetic.””

The move by Cannes organizers signals a tension between the festival's role as a high-fashion runway and its identity as a formal cinematic institution. By curtailing 'stunt' fashion and overly revealing attire, the festival is prioritizing the collective atmosphere of the event over individual viral moments, potentially limiting the creative freedom of designers in exchange for a more controlled brand image.
