Updated May 22, 2026 — 11:23am,first published May 13, 2026 — 11:42amThe red carpet at the 2026 Cannes Film Festival has more dressing rules than a strict Catholic girls’ school. It looks like rule breakers Demi Moore, Tilda Swinton and Bella Hadid won’t be elected school prefect this year.The official website for the film festival stipulates that guests at the Grand Théâtre Lumière wear a long dress or tuxedo. You can get away with a little black dress, dark-coloured pantsuit, “a dressy top with black pants” but nudity, sneakers and tote bags are forbidden, along with “voluminous outfits, in particular those with a large train, that hinder the proper flow of traffic”.Here are the red carpet rebels throwing caution to the wind in the south of France.Bella Hadid in SchiaparelliBella Hadid in delicate lace on the Cannes Film Festival red carpet, May 20.Getty ImagesAt a screening of La Battaille De Gaulle: L’Âge De Fer, supermodel Bella Hadid pays tribute to Jane Birkin.Getty ImagesGood luck slapping supermodel Bella Hadid with a fine in a haute couture gown by Daniel Roseberry for Schiaparelli.With a see-through effect and train, Hadid bent the rules in tribute to actress and fashion icon Jane Birkin’s Cannes Film Festival outfit of 1969. On that occasion, the woman who lent her name to Hermes’ most famous handbag wore a Pucci dress backwards to create a plunging neckline.Hadid turned to the Schiaparelli atelier for an embroidered update that took 22,160 hours to make.Jane Birkin with Serge Gainsbourg at the Cannes Film Festival in 1969.Gamma-Rapho via Getty ImagesTilda Swinton in ChanelTilda Swinton at the screening of La Bola Negra at Cannes Film Festival on May 21.Getty ImagesTilda Swinton in Chanel haute couture at the Cannes Film Festival.AP Photo/Andreea AlexandruTilda Swinton’s velvet two-piece with lavish silver embroidery hardly qualifies as dark trousers and a going-out top, but the Cannes Film Festival organisers can take their arguments to Chanel creative director Matthieu Blazy.In a forum on AI at Cannes, Swinton said: “I believe as long as what we’re not producing is formulaic and in some way tiring for the audience, AI doesn’t have a chance.”Swinton brought the same element of surprise to the red carpet.Demi Moore in Self-PortraitDemi Moore sports a shorter hairstyle and a dress from Self-Portrait at the Cannes Film Festival.FilmMagicDemi Moore is a jury member at this year’s Cannes Film Festival.AP Photo/John LocherAs a member of this year’s official jury, along with Hamnet director Chloé Zhao, Ruth Negga and Stellan Skarsgård, The Substance actor Demi Moore must have diplomatic immunity on the Cannes Film Festival red carpet.The train of her custom Self-Portrait dress, worn to a screening of La Pola Negra, defied the rules. The label is a favourite of Catherine, Princess of Wales.Earlier in the festival, Moore tested her immunity in a voluminous dress with gigantic bow and deliberate fraying from French label Matières Fécales. The label, which translates to Fecal Matter, has not been worn by the Princess of Wales.Demi Moore in a Matières Fécales dress at a screening of Paper Tiger on May 16 at the Cannes Film Festival.Getty ImagesKristen Stewart in ChanelKristen Stewart in Chanel at a screening of Full Phil at the Cannes Film Festival on May 16.Getty ImagesKristen Stewart sticks to her boots in Cannes.Getty ImagesTwilight actress Kristen Stewart does not seem like a person who dwells on rule books.The Cannes Film Festival organisers request “elegant shoes and sandals with or without a heel (no sneakers)” on the red carpet.Her black-and-red embroidered dress from Chanel’s autumn/winter 2026 collection meets the brief, but her vintage KOZAK 72 sneakers are a red flag.
