The 2015 Cannes Film Festival is in full swing, with one of the most anticipated red carpet events of the season happening Thursday evening.
The world's most famous models, celebrities, designers and more attended the 22nd annual amfAR Cinema Against AIDS gala, a charity event held at the Hotel du Cap-Eden-Roc in Antibes.
Naturally, the stars brought all the stops with jaw-dropping gowns featuring thigh-high slits, sexy cut-outs and plunging necklines. But hey, if there's any occasion to go all-out, it's this one.
