Elle Fanning made her latest appearance on the 2025 Cannes Film Festival red carpet on Friday. The actress attended “The Mastermind” premiere alongside the film’s stars Josh O’Connor, Alana Haim and more.

For the film’s red carpet premiere, Fanning opted for a custom design courtesy of Valentino Haute Couture. The long-sleeve gown featured a plunging neckline to Fanning’s waist. The look included a flowing skirt with a short train.

The gown was crafted with a cinched waist for added silhouette definition. All over the dress were crystal embellishments and sequin detailing. An embroidered diamond shaped pattern was featured on the sleeves, bodice, and top half of the skirt.

The ensemble carried a whimsical and feminine effect with contemporary design and detailing. Along with the dress, Fanning wore shoes courtesy of Le Silla. She accessorized with jewelry pieces from the Cartier vaults.

Fanning’s hair was styled with a slight side part courtesy of stylist Jenda Alcorn. Her makeup featured soft elements with bold brows and a light pink lip by artist Erin Ayanian Monroe. Fanning’s look was curated by stylist Samantha McMillen, who also put together Ana de Armas’ look for the Oscar-nominated actress’ red carpet appearance at the “Ballerina” premiere in London.

Prior to her latest Cannes red carpet appearance, Fanning attended the premiere of “Sentimental Value,” in which she stars alongside Renate Reinsve and Stellan Skarsgård. For the special occasion, Fanning wore a custom strapless gown courtesy of Armani Privé. The dress included such design elements as a plunging sweetheart neckline with a formfitting silhouette and allover ornate sequin detailing.

The 2025 Cannes Film Festival concludes on Saturday. 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.” Berry and Jeremy Strong, among others, serve on the 2025 jury alongside jury president Juliette Binoche.
