The 78th Cannes Film Festival is coming to a close, and while there’s been plenty of buzz around the films, the fashion has also made headlines. This year’s festival introduced new guidelines for red carpet attire. Some celebrities adhered to these rules, while others chose their own path. Regardless, there were numerous memorable outfits that sparked conversations, which you can explore in the photo gallery above.

Heidi Klum, host of “Project Runway,” defied the festival’s restriction on wearing extravagant gowns with lengthy trains. She made a grand entrance on May 13 at the festival’s opening ceremony in a pink floral Elie Saab gown complemented by an impressive train. Later, for the amFar event at Cap d’Antibes Hotel du Cap-Eden-Roc, she opted for a black Yara Shoemaker dress paired with a feathered cape. Since this event wasn’t on the main Cannes red carpet and was held outdoors, her choice didn’t violate the nudity guidelines.

At the Kering’s 10th Annual Women in Motion dinner on May 18, Nicole Kidman, known for her role in “Nine Perfect Strangers,” was celebrated. She captivated the audience in a striking red lacy Balenciaga gown.

Eva Longoria told People she brought six (!!) trunks of “dresses and changes and shoes and bags and jewelry.” She wore a custom turquoise Elie Saab gown for the “Mission Impossible: The Final Reckoning” premiere. And she donned a blush pink Tamara Ralph strapless gown at the “Phoenician Scheme” premiere.

Elle Fanning’s shimmery strapless Armani Privé gown turned heads at the May 21 “Affeksjonsverdi” (Sentimental Value) premiere. The dress was all about the details, including the soft pink flowers on the bodice and train.

Dior ambassador Natalie Portman paid homage to the early days of the iconic fashion house at the Cannes premiere of “Eddington.” She wore a strapless black and silver custom creation that was a throwback to a 1951 archival gown.

“9-1-1” star Angela Bassett attended the “Mission: Impossible – The Final Reckoning” premiere in a navy and black Burberry dress with fringe sleeves and skirt.

Emma Stone is always a style star. At the “Eddington” premiere at Cannes, the Louis Vuitton ambassador wore a sculptural white gown from the brand with a dramatic bib-like neckline.

Another style star is Kristen Stewart, who is a Chanel ambassador. And at Cannes, her looks were both classic and cool, putting a new twist on shorts suits! For the “Bono: Stories of Surrender” carpet, Stewart donned Bermuda-like shorts, a sheer top and black tie. And for “The Chronology of Water” photo call, the actress wore a pink tweed short suit covered by a sheer maxi skirt, so as not to break the “no nudity” rule.

And finally, Alexander Skarsgard had the internet buzzing when he walked “The Phoenician” red carpet in a double-breasted jacket rocked thigh-high leather St Laurent boots. Classic on the top, edgy on the bottom!
