Natasha Poly, Hana Cross, Joan Smalls and Cindy Bruna all stunned in very daring looks on Thursday as they led the red carpet arrivals for the amfAR charity gala at Hotel du Cap-Eden-Roc during the Cannes Film Festival.

The models slipped into very risqué ensembles, leaving almost nothing to the imagination in their barely-there dresses for the swanky Cannes party which could be the most daring gala to date. 

Russian model Natasha (36), turned heads wearing a skimpy dress as she displayed her amazing figure and showed off her sparkling bra.

This black gown featured long sleeves and a high neck. The lacing ran from her hips to her waist. 

Natasha’s height was increased when she put on a pair of high-heeled peep toe boots to finish her stunning look.

The blonde beauty had her tresses styled poker straight as they fell behind her ears whilst she added a shimmering highlight to her chiseled cheekbones.

Jaw-dropping: The black dress featured a high neck and long sleeve, before opening at the chest and tying down the Russian supermodel's torso and hips

Perfection: She layered it over a glitzy triangle bralette, with a pair of lace-up heeled boots

Amazing: Natasha’s black, high-necked dress was breathtaking. It opened at the chest to expose the supermodel from Russia’s hips.
