Heidi Klum joins the rule-breaking club with her long train at Cannes after Bella Hadid¡¯s bold defiance

Heidi Klum joins the rule-breaking club at Cannes 2025, and she did it in the most dramatic way possible! The iconic model and red carpet risk-taker showed up to the opening ceremony of the Cannes Film Festival in a dreamy, cotton-candy pink Elie Saab gown that looked like it belonged in a couture fairytale. But that glorious train trailing behind her? It broke one of the festival¡¯s brand-new fashion rules.

Cannes red carpet rules: No nudity, no drama

Cannes¡¯ updated red carpet dress code specifically bans voluminous gowns with large trains, stating they ¡°hinder the proper flow of traffic¡± and complicate seating arrangements. But Heidi, clearly not one to be tamed by traffic logistics, swanned in like the queen of chaos¡ªher gown breezing through regulation like it did not even exist.

Paired with pointy metallic pumps and dripping in Lorraine Schwartz jewellery, the 51-year-old former Project Runway judge brought glamour, defiance, and just the right amount of fashion anarchy. And she is not alone in this couture rebellion.

Bella Hadid broke the rule first

Bella Hadid, another Cannes regular, ignited the fire on day one with a jaw-dropping black Saint Laurent gown that tiptoed around the ¡°no nudity¡± rule. With exposed sides, an asymmetrical strappy back, and a slit that soared up to the heavens, her look had everyone asking: is this allowed?

Technically, there was no ¡°graphic nudity,¡± so Bella walked, and twirled, freely, accessorised with a massive 118.68-carat emerald earring set and a heart-shaped diamond ring fit for royalty.

Halle Berry's last minute dress drama

Meanwhile, Halle Berry, who is sitting on this year¡¯s Cannes jury, was not so lucky. The Oscar winner had to ditch a stunning Gaurav Gupta gown at the last minute because, you guessed it, the train was too extra. Speaking about it earlier in the day, she explained that she had to pivot to a less voluminous look, eventually showing up in a dramatic, ruffled Jacquemus number that still served but kept her within regulation limits.

So what does this all mean? The new Cannes rules are technically in place, but if Bella and Heidi¡¯s entrances prove anything, it is that fashion rules are made to be stylishly broken, especially on the most glamorous carpet in the world.
