Bella Hadid’s skimpy swimsuit is completely open on the back and sides

Bella Hadid may be the queen of the Cannes Film Festival red carpet, but her off-duty looks are every bit as eye-catching.

In between captivating the crowds with her glamorous premiere gowns, the 29-year-old supermodel worked on her tan in some very stylish swimwear — including a white-hot one-piece that revealed more than it concealed.

Hadid shared a few Instagram Story snaps over the weekend of herself soaking up the French Riviera sun in an Indah swimsuit described by the Bali-based brand as “the perfect balance between skimpy style and customizable coverage.”

Featuring a completely open back and sides along with a deeply plunging neckline, the style is finished with a trio of adjustable ties that allow the wearer to find their perfect fit — not to mention show as much skin as they desire.

Hadid finished her boat-day look with a crochet headscarf, Chanel sunglasses and gold hoop earrings.

The racy one-piece isn’t the only memorable swim style Hadid’s sported during her time in Cannes; the brunette beauty was also spotted doing yoga in a metallic bikini while aboard a yacht, and posing for pics in a striped Prada maillot.

Hadid also showed off a parade of gorgeous gowns while at the French film fest, including a white lace Schiaparelli Haute Couture look inspired by an iconic dress Jane Birkin wore at Cannes in 1969.

With the same dangerously low-dipping neckline and black brooch as Birkin’s original gown — which the “Blow-Up” actress famously wore backwards — Hadid’s bespoke design called for 22,160 hours of embroidery work.

Other standout styles included Hadid’s gray satin Prada gown and matching cape for the “Garance” premiere and the archival gold Elie Saab Couture dress she chose for the Chopard Miracle Gala.
