Talk about a royally good red carpet look.

French-Russian actress Anastasia Andrushkevich channeled Princess Diana at the Cannes Film Festival earlier this week, attending the “Fjord” premiere in an ice blue dress that was almost identical to one the late royal wore at the same event in 1987.

Custom-designed by Mehmet Ozden, as reported by Vogue, Andrushkevich’s gown featured a strikingly similar strapless silhouette, structured bodice and flowing skirt.

And just like Diana, the actress accessorized with a matching scarf that draped down her back.

Even Andrushkevich’s short blond bob seemed to echo the princess’ 1980s ‘do.

Diana’s original gown was designed by Catherine Walker, who is still a current favorite of Kate Middleton’s, was last sold at auction in 2011 for $137,500.

It was originally inspired by Grace Kelly’s Edith Head gown from “To Catch A Thief,” giving this latest Cannes look even more historical context.

The 1955 Hitchcock film was actually filmed in the French Riviera, making Diana’s homage to the look all the more fitting.

The late royal also wore the gown on two other occasions: for a portrait sitting in 1987 and at a September 1989 performance of “Miss Saigon” at the Theatre Royal.
