Elsa Hosk Cinderella Dress at Cannes

As we know, Cannes Film Festival is not just any red carpet event—especially when you're sharing the carpet with seasoned vets like Nicole Kidman, Julianne Moore and Diane Kruger in their custom couture. So being a Cannes rookie means you must bring your A-game. Sparkle, shine, volume! Or when in doubt, channel a Disney princess.

Victoria's Secret Angel Elsa Hosk stepped up to the plate today for the highly anticipated premiere of The Beguiled, starring Kidman, Elle Fanning and Kirsten Dunst.

The Swedish supermodel brought a touch of Cinderella magic to the premiere in a custom Alberta Ferretti powder blue off-the-shoulder gown with thigh-grazing slit. No supermodel look is complete without a slit, of course. Her old hollywood waves, and diamond earrings finish off the fairytale look to perfection.

She even had a little helper to make sure she always looked her best.

While this was her first actual premiere, Hosk hit the star-studded de Grisogno party in Cannes last night in a sheer, disco-ready Alberta Ferretti gown alongside fellow IMG faces Cami Morrone and Hailey Baldwin.
