Irina Shayk attended a party at the Cannes Film Festival while wearing see-through lingerie and diamonds

• Irina Shayk made a daring fashion appearance at the Cannes Film Festival on Monday.
• She attended a party wearing Gucci lingerie, a see-through slip, and diamond accessories.

Diamonds — and lingerie — are a girl's best friend.

Irina Shayk proved that at the 2023 Cannes Film Festival on Monday when she was photographed at Hôtel Martinez wearing both as part of a skin-baring Gucci outfit.

She donned a mesh bra and matching string underwear — both with a monogram Gucci print — covered by a mesh slip with diamonds draped down her chest from its neckline.

The model also added mesh gloves, knee-high stockings, red lipstick, and black sunglasses.

Speaking with CNN during the festival, Shayk explained that she and her fashion "have evolved" over the past decade.

"This is a new time with a new vision, and I wanted to use the moment and different outfits to have fun, be free, and express a different side of my personality and creativity," she said.

Shayk also added that while she once felt nervous on red carpets, she doesn't anymore.

"I feel more comfortable in my own skin, and I wanted my wardrobe in Cannes to show that I can be a mom — I can be a working mom — and still show up, be stylish, and express myself," she said.

Shayk's first appearance at the film festival this year displayed that perfectly. She wore a glamorous Giorgio Armani Privé gown crafted from navy-blue tulle and matching crystals with strappy black sandals and diamond jewels.

But the look was also daring. Not only was the mesh gown semi-sheer, but it also had a plunging neckline and deeply-cut sleeves that revealed part of her chest.

"What is expected at Cannes is beautiful and elegant gowns, and I wanted to have a little bit of fun with that," she told CNN about the look.

She also had a standout fashion moment on the "Firebrand" red carpet wearing a leather ensemble from Mowalola. The black-and-red two-piece included a crisscross bra and a low-rise skirt, both of which she wore with a diamond necklace from Messika.

Shayk told CNN that the look was "very different" for her, but a way to "bring something new" to the red carpet.

"I want to see a different type of fashion at Cannes," she told the publication. "I wanted to take a different, modern approach and think, 'What does the young generation want? What would my 6-year-old daughter want to wear when she is 18?'"

And she knows it's a controversial choice, describing the look to CNN as "out there" and "strong."

"I knew so many people were going to criticize it. But I think people are going to look back at it in a couple of years and change their opinion," she said. "With fashion, you always have to break the rules a little bit. And often, when you go back in time and look again at these things, you realize, 'That was actually amazing.'"

But at the end of the day, Shayk is confident in her fashion. And most importantly, she's having fun with it.

"The Cannes red carpet was the opposite of my everyday life. And that's kind of why I enjoy it so much," she told CNN.
