Natalie Portman wore a dazzling recreation of a 1949 Christian Dior gown housed at The Met to the Cannes Film Festival

• Natalie Portman wore a sparkling recreation of a late-1940s Christian Dior gown Saturday.
• The actress was attending the premiere of her film "May December" at the Cannes Film Festival.

The bejeweled gown Natalie Portman wore to the premiere of her latest film at the Cannes Film Festival was inspired by a museum-worthy piece.

The actress stepped onto the red carpet with her "May December" costars Charles Melton, Julianne Moore, and Cory Michael Smith on Saturday in a sparkling strapless gown. The bone-colored dress featured a voluminous, scalloped skirt with layers of ornate blue beading.

According to Women's Wear Daily, the custom Christian Dior piece was inspired by the "Junon" dress from the designer's 1949-1950 fall/winter collection. The original dress is part of The Costume Institute's collection at The Metropolitan Museum of Art, although it's not currently available to view.

Dior's initial design was a reference to Juno, the Roman goddess most closely resembling the Greek goddess Hera, per the museum's website. The Met regards "Junon" and another dress from the same year, "Venus," as two of the "most coveted of his 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," the website reads.

Over the weekend, Portman paired her version with platform peep-toe heels and diamond drop earrings. Her hair was pulled into a slicked-back bun that gave way to nude makeup and glittery silver eyeshadow.

The "Black Swan" star hit the red carpet in another strapless Dior gown in a similar color scheme for the premiere of "The Zone of Interest" on Friday. She wore her hair down with the slim, sequin dress and paired it with a statement necklace from Chopard, according to W Magazine.

Portman's outfits weren't the only things stealing the show at Cannes — Deadline reports "May December," a story about an actress researching a scandalous tabloid romance, earned an eight-minute standing ovation at the festival.
