Emma Stone wore custom Louis Vuitton and High Jewelry to the premiere of her movie “Eddington” at the 78th Cannes Film Festival on Friday. The star wore a gown courtesy of the French luxury fashion house, for which Stone has served as a brand ambassador since 2017.

The Oscar winner was styled by Petra Flannery in the look created by Nicolas Ghesquière, artistic director of women’s collections. She wore a sleeveless white silk crêpe gown with a light silk satin asymmetrical topstitched bib and white satin Gala sandals. The dress featured a slight train, which her costar Pedro Pascal assisted her with on the red carpet for the premiere.

Her jewelry was from the Louis Vuitton High Jewelry Awakened Hands, Awakened Minds collection. She wore the collection’s Seduction Earrings set with two octagonal-cut emeralds and the Phenomenal Ring set with one LV Monogram Star-cut diamond. She wore her short hair pulled back and tucked behind her ears, and kept her makeup minimal with a light pink lipstick.

Stone stars in the Ari Aster-directed “Eddington,” which also features Joaquin Phoenix, Pedro Pascal, Luke Grimes, Deirdre O’Connell, Micheal Ward and Austin Butler.

Angelina Jolie also attended the premiere wearing a gown by Bruno Cucinelli.

“Eddington” follows the political and social turmoil in the fictional city of Eddington, N.M., during the COVID-19 pandemic. The film will be released in theaters on July 18.

Stone has appeared in multiple Louis Vuitton campaigns over the years for handbags and clothing. Stone also frequently wears Vuitton on the red carpet, including at the Oscars in March. She wore a shimmering, custom sleeveless dress that featured silver sequins and an A-line skirt, with a slightly cinched waist that defined her silhouette.
