Amal Clooney returned to Cannes Film Festival sans husband George Clooney last night, walking the red carpet to attend the screening of her friend Bono’s documentary, Stories of Surrender. The human-rights lawyer and celebrated humanitarian can more than hold her own when going solo and opted to stick to the glamorous dressing style—and vintage choices—that makes a standout Amal Clooney evening look.
Clooney stepped out at the Palais des Festivals in an archival John Galliano–era Christian Dior gown that was full-length with a dramatic train, sweetheart neckline, and waist-nipping silhouette. While it’s very much in keeping with her red-carpet fashion formula, it was a quiet break with the newly instated Cannes Film Festival dress code. The recent rules have garnered the most attention for banning nudity and more risqué dresses, but they’re also trying to stop more voluminous, dramatic looks—that include trains.
