Anne Hathaway just struck style gold in Gucci.

The actress attended at photo call at the 75th annual Cannes Film Festival on Friday in a black-and-blue Gucci minidress that dazzled from all angles. The minidress featured an electric blue cone-like bustier top, black sequins and a tie-back detail.

Hathaway, 39, accessorized the statement look, styled by Erin Walsh, with Bulgari diamond earrings — the actress is the new global ambassador for the high jewelry brand — and towering metallic silver heels. A pair of retro gold-and-green cat-eye sunglasses brought it all home for a perfect nod to 1960s chic.

The Oscar winner made her debut at Cannes this week for her movie Armageddon Time, a James Gray-led period film also starring Jeremy Strong and Anthony Hopkins — and she brought her uncanny sense of style with her.

Previously, Hathaway stunned in her opening red carpet look, appearing in an ethereal white two-piece sequin Armani Privé gown with voluminous sleeves attached to a train, Bulgari gems and Santoni heels.

This year’s festival marks the actress’s first-time appearance at the landmark industry event.

“You hire [stylist] Erin Walsh and you trust her,” Hathaway tells PEOPLE of the secret to the perfect Cannes wardrobe. “You know, I’ve never been to Cannes, and I’ve been watching the fashion of the film festival unfold for a couple decades now. And I’ve noticed certain things you can never go wrong with.”

She added: ​​”You never go wrong with a little sparkle. You never go wrong with something that looks chic and glamorous, but feels very, very comfortable. And I noticed that a lot of my favorite actresses had their first experience wearing all white,” continued the Academy Award winner. “So that was what I did.”

In January, Hathaway posted a photo debuting new wispy bangs and a collared floral mini dress. Though the ensemble wasn’t by Prada (the dress, coat and shoulder bag are Valentino, the boots are Giuseppe Zanotti, and the jewelry is Bulgari), fans immediately noticed a resemblance between Hathaway and Andy’s style.
