"I think my sense of style is all about embracing silhouettes from the past, especially feminine silhouettes, and making it modern," the actress said. "I love the actresses of the 1940s and '50s and '60s, and I think Calvin Klein does do that."

This style inspired the dress that Chastain wore to the Golden Globes, where she took home the statuette for Best Performance by an Actress in a Motion Picture - Drama.

"[Women's Creative Director of Calvin Klein] Francisco [Costa] designed my Golden Globes dress and I really felt it was like Rita Hayworth -- the silhouette -- but he made it very modern and striking and interesting," said Chastain.

Olivia Wilde voiced a similar perspective, saying, "Francisco always comes up with something really modern and really cool while maintaining that chic simplicity ... It's not over-the-top and that's why it's always timeless."

As for what Chastain has in mind for the Oscar red carpet, she told us, "I'll probably wear color. I won't be the wallflower at the Oscars -- that's for sure."
