Bella Hadid attends the "Tre Piani (Three Floors)" screening during the 74th annual Cannes Film Festival on July 11, 2021 in Cannes, France.

Bella Hadid may have debuted her most daring red carpet look to date at this year’s Cannes Film Festival at the premiere of Tre Piani (Three Floors).

The supermodel delivered major drama wearing an avant-garde gown from the Schiaparelli Haute Couture fall ’21 collection, Yahoo! Life reports. Made from wool, the form-fitting dress featured a revealing open neckline that cut below Hadid’s cleavage. The dress was also designed with on-trend puff sleeves.

Hadid’s neckline is what seems to have caught everyone’s attention — with a gold-dipped bronchial tree necklace adorned with rhinestones (also Schiaparelli Haute Couture) that covered her baring chest. The jewelry, designed to look like a lung passageway was paired with a high-fashion sleek updo. As for footwear, Hadid opted for strappy black sandal stilettos.

When it comes to her wardrobe, Hadid is known to take fashion risks: she’s a fan of retro dressing, opting for looks from the ’70s, ’90s and early 2000s. As for her red carpet moments, she often channels Old Hollywood. Her favorite brands include: Dior, Alexander Wang, Prada, Givenchy and Tom Ford.

Tre Piani is a 2021 Italian-French drama film co-produced, co-written and directed by Nanni Moretti. It’s based on the 2017 novel Shalosh Qomot by Israeli writer Eshkol Nevo, moving the setting from Tel Aviv to Rome. Moretti also stars in the film. You can watch the trailer below:
