19 Shameless Looks That Prove Cannes 2026 Was The Latest Victim Of Provocative Outfits

8. Emma Mackey

Emma Mackey, who rose to global fame through Sex Education before starring in Barbie , attended the festival as part of the Full Phil cast alongside Kristen Stewart and Woody Harrelson. For the midnight premiere screening, Emma wore a custom all-white Louis Vuitton evening gown styled by Jamie Mizrahi. The dress featured a conservative high neckline, long sleeves, and floor-length silk construction. However, the minimalist silhouette featured a dramatic inverted plunging cut-out running down the front of the gown, exposing much of her torso beneath the structured fabric. An integrated scarf detail flowed behind her as she ascended the Palais des Festivals staircase, adding soft movement to the otherwise sleek silhouette. She completed the ensemble with Louis Vuitton High Jewelry pieces, while her blonde bob was styled into soft waves and paired with fresh, radiant makeup. Due to its more conservative structure, Mackey’s gown aligned closely with Dr. Naomi’s observation that “there are so many wonderful gowns… which become more memorable than the see-through, body-exposing outfits, which may catch attention, but do not always radiate sophistication or favorable media attention.”
