Bella Hadid Debuts Blonde Hair in Saint Laurent Dress at Cannes 2025

Bella Hadid was among the high-profile figures who attended the opening ceremony and “Partir Un Jour” (Leave One Day) screening at the Cannes Film Festival on Tuesday. The model joined such stars as Julia Garner, Eva Longoria and Cannes Film Festival jury president Juliette Binoche for the first major screening.

For the red carpet occasion, Hadid wore a dress courtesy of Saint Laurent by creative director Anthony Vaccarello. Hadid’s look featured a cross-back dress with a thigh-high slit in silk satin. The dress created an asymmetric aesthetic for contrast and angularity.

Hadid complemented the dress with the Georgia sandals in saint crepe and rhinestones from the French luxury fashion house. As for her accessories, Hadid opted for earrings featuring 118.68 carats of emeralds and 10.31 carats of diamonds set in 18-karat white gold from Chopard‘s Red Carpet Collection. More jewelry pieces worn by the model included rings from the Haute Joaillerie Collection.

Hadid’s Cannes red carpet look was further augmented by her new blond hairdo. The model styled her look with a side part and dusty blond tone. When it came to her makeup, Hadid’s visage included lined brows, smokey eyes and a neutral lip.

Hadid returned to the runway, following a short hiatus, for Saint Laurent during Paris Fashion Week last March. Hadid modeled a look from the house’s fall 2025 ready-to-wear collection. In 2024, Hadid disclosed to WWD that she was taking a step back from modeling to focus on her mental and physical health.

“Treatment was painful, I have to be honest, and to be away from work for the first time in 10 years, I realized I was a workaholic,” Hadid told WWD in January 2024. The model often uses social media as a way to address her treatment for Lyme disease and chronic disease.

The 2025 Cannes Film Festival begins Tuesday and concludes May 24. Films premiering at this year’s festival include Wes Anderson’s “The Phoenician Scheme,” Julia Ducournau’s “Alpha” and Lynne Ramsay’s “Die, My Love.”
