Charli XCX made a memorable appearance at the 78th Cannes Film Festival in May 2025, attending the Kering Women In Motion Awards and the Cannes Film Festival Presidential Dinner. She wore a custom Saint Laurent gown in soft lilac—a sheer, slip-style dress with a plunging V-neckline and delicate spaghetti straps. The flowing silhouette was paired with an oversized feathered shawl and diamond jewelry from Boucheron, creating a look that was both glamorous and understated. Her signature minimal makeup and natural hairstyle completed the ensemble, marking a departure from her usual bold "Brat" aesthetic.
During the event, which honored Nicole Kidman, Charli XCX mingled with fellow attendees including Paul Mescal and Dakota Johnson. The evening celebrated women's contributions to cinema and featured a dinner at the historic Place de la Castre. Charli's presence at the festival highlighted her evolving fashion sense and her engagement with the film industry, further solidifying her status as a multifaceted artist.
Beyond the red carpet, Charli XCX also participated in the Magnum Cannes beach party, where she served as the event’s DJ alongside The 1975’s George Daniel. Her involvement in both high-profile events and more relaxed gatherings showcased her versatility and ability to connect with diverse audiences. Her appearances at Cannes 2025 were noted by fashion critics and fans alike, with her Saint Laurent gown being featured in several best-dressed lists.
