The 76th annual Cannes Film Festival brought Hollywood's biggest movie stars to France to showcase the hottest up-and-coming flicks.

While cinema was the reason for the season, fashion kept the red carpet buzzing as barely-there ensembles ruled the Palais des Festivals.

Irina Shayk stood out from the crowd wearing a unique black leather strap fashioned into a crop top with a matching skirt at the "Firebrand (Le Jeu De La Reine)" premiere.

The film, directed by Karim Aïnouz, reportedly received a host of praise inside the theater, but all eyes were on Gigi Hadid, Ashlee Simpson and Alicia Vikander on the red carpet.
