Miranda Kerr, Charlize Theron, Emma Stone: Cannes Film Festival Fashion Days Two and Three

— -- The Cannes Film Festival may be a celebration of film, but it's also a chance for stars to experiment with fashion.

From Charlize Theron to Emma Stone, Hollywood and fashion A-listers (below) have been hitting the red carpet in bright colors, fun patterns and interesting silhouettes.

However, last night, all eyes were on Miranda Kerr, who stunned in an Emanuel Ungaro gown with a plunging neckline and thigh-high slit.

Kerr, 32, isn't at the festival to promote a movie. Instead, she's promoting Magnum ice cream.

Her red carpet turn came two days after Lupita Nyong'o wow'd at the festival's opening ceremony, wearing a custom Gucci gown with intricate embroidery.

"It's #GrasshopperGreen for @festivaldecannes opening night. Thank you @Chopard @Gucci and Uganda's women for the hair inspiration. #NseneneSeason #cannes2015," she wrote on Instagram at the time.
