The Worst-Dressed Celebs At The 2025 Cannes Film Festival

If celebrity fashion is your passion, then the Cannes Film Festival would be one of your favorite annual events. Every May, the rich and famous flock to the south of France and offer up a delectable array of style for the daytime photo calls. The vibe is seaside chic, the grandiose red-carpet premieres put the world's most famous designers' work on display, and the glamorous evening galas invite celebrities to bring their fashion A-game. But what's a global who's-who event without a few fashion fails?

Attendees and their stylists were given an extra challenge this year: There was a dress code for the 2025 Cannes Film Festival, which some celebs broke immediately. For the first time, the festival banned overly voluminous gowns for practicality reasons, along with dresses that were too sheer. So, who eschewed the rules? Were any of the worst-dressed celebs from the Cannes Film Festival in 2024 repeat offenders? No, the 2025 list of worst-dressed celebs at the Cannes Film Festival is full of newbies, including a dowdy-looking Julia Garner, a disproportionate Hayley Atwell, and a rule-breaking Heidi Klum.

Is it possible that Julia Garner and her stylist didn't know there was a change to the dress code and planned for her to wear a sheer dress, so they rushed to the boutique in the hotel lobby and found this number? No, we think this was the intentional look, unfortunately. The gown, a Haider Ackermann for Tom Ford design, wasn't helped by the jarring additions of black heels and vampy lips. We've seen Garner do much better, so we expect this is just one misstep in her fashion 'folio.

This was an example of weird fashion on the Cannes Film Festival red carpet happening to good people. It almost looked as if Emma Stone decided to play around in the wardrobe department and found a piece from a nun's costume, or perhaps a giant baby bib. Regardless, the collar on her Louis Vuitton gown felt distracting on an otherwise beautiful look.

Heidi Klum was one of the celebrities that ignored the rule banning voluminous trains on the Cannes Film Festival red carpet for 2025, wearing two Elie Saab gowns with fabric trailing behind. But the offending didn't end there. The metallic dress she wore to the "Mission: Impossible — The Final Reckoning" premiere was one of the most unflattering looks we've ever seen on the supermodel, perhaps because the mirrored effect distorted the light as it hit her famous curves. Unfortunately, Klum also made it onto our recent list of the worst-dressed celebs at the 2025 Met Gala.

Swedish TV personality Victoria Silvstedt wins the prize for most confusing dress at the 2025 Cannes Film Festival. Her Nabil Younes gown had so much going on, it was hard to take in. But the biggest question of all: What was the point of that piece of fabric extending from the crotch?

Fans of Farhana Bodi, who's known for Netflix's "Dubai Bling," know that she can deliver some seriously stunning fashion when she wants to. This wasn't one of her top moments, however. For starters, the Barbiecore trend feels passé in 2025. Also, there would have been enough drama with the pointy embellishment at the chest — no OTT pink ruffle necessary.

Another look that felt unnecessarily OTT was "Mission: Impossible — The Final Reckoning" star Hayley Atwell's red Giambattista Valli number. Having two voluminous skirt poofs felt imbalanced on her lithe frame (in addition to breaking the 2025 rules). Then, there was the color. She practically blended into the Cannes red carpet, which explains why we don't see a lot of the shade at the event. Celebs are there to be seen, after all. 

French actor Frédérique Bel was another celeb who turned her nose up at the Cannes Film Festival dress code by donning revealing looks on multiple occasions. The bizarre gold sequined gown exposed major side boob, while the black dress she rocked to the "Highest 2 Lowest" premiere didn't leave much to the imagination. And let's not ignore her unique accessories. We're all for a little whimsy in fashion, but somehow her French-fry clutch and mini hat missed the mark.
