Bella Hadid showed off her model physique in a slinky red silk custom Alexandre Vauthier Couture gown at the premiere of “The Unknown Girl” during the Cannes Film Festival Wednesday.

The in-demand model stole the show in the extremely racy red cleavage and thigh-baring gown. The 19-year-old showed off her endless legs, cleavage and toned arms.

The younger sister of Gigi Hadid made waves at the opening of the 69th Cannes Film Festival when she attended with her boyfriend The Weeknd during the premiere of “Café Society.” Fresh off her opening at the Misha Collection show in Sydney during Australia Fashion Week on Monday, Bella raised the style stakes. The custom gown is from the Italian designer’s Spring 2016 Couture collection.

Bella’s gown is a custom version of the haute couture designer’s Look 34. The show-stopping gown featured a wrap style, delicate spaghetti halterneck, bias cut, a slinky skirt with a long train and a thigh-baring split. The bodice of the gown also featured a dangerously lunging neckline that left little to the imagination.

The beauty accessorized with a pair of teardrop shaped earrings and a chunky diamond bracelet. She also wore a purple gemstone and diamond ring all by Swiss luxury jeweller De Grisogono. Bella paired her ensemble with black strappy sandals from Giuseppe Zanotti Design.

Bella also showed off her new fringe in her messy up ‘do’, which was done by her stylist Jen Atkin.

The side-swept bangs added a sexy and gothic vibe to her long raven tresses and framed her flawless bone structure. Bella kept her make-up minimal to draw attention to her gown. The model wore deep pink lipstick, pink blush and smudged eyeliner.

The model kept on adjusting her gown as she posed for photographers on the famous steps, in order to avoid wardrobe malfunction. Bella’s gown was reportedly one of the most daring gowns on the Cannes red carpet.

Bella Hadid might be the younger sister to top model of the moment Gigi Hadid-but she's certainly putting in the effort to make sure everyone knows the name Bella too.

The custom dress featured a slit all the way up to her hip bone, which she paired with black sandals from Giuseppe Zanotti Design.

Bella also proved to be a model in demand this week, on Monday she opened the Misha Collection show in Sydney during Australia Fashion Week.

Prior to that, Hadid made her first appearance at Cannes Film Festival at the opening ceremony and premiere of Cafe Society. It's still days away until Cannes Film Festival comes to a close on May 22nd, but Bella Hadid just raised the stakes very high.
