JUST WHEN you thought you'd seen almost every part of Bella Hadid's supermodel figure - she gets her Cannes out on the red carpet of an AIDS gala dinner in France.

Sticking to recent tradition, the 20-year-old model arrived at the amfAR gala red carpet on Thursday at the Cannes Film Festival, wearing little more than a sheer draping of see-through, crystal-embellished fabric and a pair of oversized nude coloured underpants.

Wearing a one-shouldered gown designed by London-based duo Michael Russo and Tamara Ralph, the frock has been dubbed the sexiest gown at Cannes - ever.

The gala event - which is helps raise funds for research programs in to AIDS - is one of the world's most successful benefit events and the most coveted ticket in town during the Cannes International Film Festival.

But even a gown as jaw-dropping as Hadid's isn't exempt from a mishap.

Teen Vogue reported that she almost suffered a huge wardrobe malfunction: While Bella did layer a pair of nude-coloured briefs under her sheer gown, she ended up baring more skin than perhaps intended, when she took a wide step on the carpet.

Twitter users were quick to comment on Hadid's frock, commenting on how stunning the model looked in the dress.

But others weren't so impressed by the nearly naked ensemble.

Hadid made headlines at Cannes last year when she wore a red dress with a split so high it raised eyebrows. It seems she has now fallen into the trap of feeling she has to keep pushing the envelope with the revealing nature of her dress - the younger Hadid feels if the dress isn't plunging, see-through or slashed to the hip, she's not doing the red carpet right.

It's like she's become addicted to shock value.

She admitted wearing the gown was "a bit scary" but appreciated the "nice feedback" she received following the red carpet.

"I've always wanted to wear a red dress, it's just been my dream since I was a little girl," she told Glamour.

"Ever since prom and freshman, it's always been what I wanted to wear but I never could. I'm usually very simple with my red carpet looks - I tend to just wear black - so this was a big risk. I was sort of scared about it, but I've had so much nice feedback which was exciting."

Earlier this week, Hadid kicked off her attendance at Cannes in a pale pink gown, with a thigh-high split.

Flashing her undies and a great deal of flesh, Hadid hit the ground running in eye-catching style.

Hadid didn't seem to care too much as her frock fell open at the front to reveal her matching pink satin underpants.
In November last year, the model wore a nearly nude gown to debut her first Victoria's Secret fashion show alongside her sister, Gigi.

Just two months later, she went braless at the Dior masquerade ball with model pal Kendall Jenner and rapper A$AP Rocky.

Earlier this month at the Met Gala ball, Hadid opted for a sheer figure-hugging Alexander Wang catsuit, which showed off every curve on her body.

Her barely there wardrobe continued in to the afterparty, when she wore a sheer black mini-dress with black tape over her nipples.

It's a brave new world - but where to from here?
