Natalie Portman’s Cannes LBD Is an Architectural Wonder

As a Cannes Film Festival veteran, Natalie Portman knows exactly how to work one of the event’s photo calls. This morning, Portman proved as much. She returned to the Croisette for the first time since 2023 in a structured minidress that recalled one of her most famous roles.

Portman attended the photo call for Arco in a Dior fall 2025 number that bore a slight resemblance to the famous feathered tutu she wore in 2010’s Black Swan. The actor’s dress featured a high-neck and cap sleeves that led into an architectural pannier skirt. Portman’s dress was embossed with black and white beads. Simple ankle-strap heels (a Portman red carpet staple), black sunglasses, and platinum and diamond Tiffany & Co. Archives earrings, a Tiffany Victoria® bracelet, and rings polished off the look.

Portman is in Cannes for the premiere of Arco on Friday evening—she has a voice acting credit in the animated film and also served as a producer on the project. The star, a regular at Cannes since 2005, last attended the film festival two years ago. Then, she was promoting the Todd Haynes film May December, and she dazzled the Croisette in a series of looks, including a historic Dior reference, for the film’s premiere. She wore a custom stunner by the French brand that was inspired by Christian Dior’s famous Junon dress from 1949.

And while looks like the one Portman wore this morning have always been a staple in her repertoire, her embrace of the LBD is right on trend this year at Cannes. Iterations of the wardrobe staple have been a popular choice for many attending the first few days of the festival, including the likes of Bella Hadid, Irina Shayk, and Zoe Saldaña. While the rise in simple, all-black dressing could be attributed to the festival’s new dress code, there’s nothing as red carpet-tested as the little black dress. Something Portman proved yet again today.
