A museum-quality object served as the inspiration for Natalie Portman’s embellished gown for the Cannes Film Festival premiere of her most recent movie.

On Saturday, the actress walked the red carpet with her “May December” co-stars Charles Melton, Julianne Moore, and Cory Michael Smith in a sparkly strapless gown. The bone-colored gown has a full, scalloped skirt with layers of elaborate blue beading.

According to Women’s Wear Daily, the bespoke Christian Dior outfit was inspired by the designer’s 1949–1950 fall/winter collection’s “Junon” dress. The original gown is in The Costume Institute’s collection at The Metropolitan Museum of Art; however, it is not presently on display.

According to the museum’s website, Dior’s first design was a nod to Juno, the Roman deity most closely resembling the Greek goddess Hera. The Met considers “Junon” and another garment from that year, “Venus,” to be two of his “most coveted designs.”

“The magnificent skirt of ombréed petals, like abstractions of peacock feathers without their “eyes,’ obliquely references the bird associated with the Queen of the Olympians,” according to the website.

Portman accessorized her version with platform peep-toe shoes and diamond drop earrings over the weekend. Her hair was pulled back into a neat bun, revealing nude makeup and sparkly silver eyeshadow.

For the premiere of “The Zone of Interest” on Friday, the “Black Swan” star wore another strapless Dior gown in a similar color scheme. According to W Magazine, she wore her hair down with the thin, sequin dress and matched it with a Chopard statement necklace.

Portman’s clothes weren’t the only thing that stole the show in Cannes, according to Deadline. At the festival, “May December,” a tale about an actress pursuing a notorious tabloid relationship, received an eight-minute standing ovation.
