The "Zero Dark Thirty" star debuted the new look via Instagram on Saturday, June 7. "Someone got a haircut courtesy of @renatocampora #hair #genius #brigittebardot #60s #fashion #iloveitsomuch," Chastain, 37, wrote of her style inspired by the sexy French actress of the '50s and '60s.

Celeb hairstylist Renato Campora, who also styled the Oscar nominee's hair for her May 17 appearance at the Cannes Film Festival, added eyebrow-length fringe to Chastain's red hair. He also added lots of loose waves and texture for a modern take on the retro style.
