Not every actress in Hollywood used up her best red carpet mojo for the Golden Globes on Sunday. Elle Fanning, for example, saved a bit of glamour for the premiere of her new film, Live By Night. While her big 2016 premiere, the Nicolas Winding Refn film Neon Demon, saw her break out as a red carpet star (and a film star to go with it) in frothy, glittering dresses by Alexander McQueen, Gucci, and Valentino — perfect for a film about a vampire model — 2017 seems to already be her year in Old Hollywood chic, just the thing for the period drama she's promoting. First up: an ultra-simple, exceedingly elegant Oscar De La Renta gown, the better of the all-white looks that graced the red carpet for the Live By Night Los Angeles premiere. There might have been some turbulence recently at the house of De La Renta (and Herrera), but on the red carpet, it's all smooth sailing.

Who: Elle Fanning.

When: Monday, January 9.

Where: The premiere of her new film Live By Night with Sienna Miller and Zoe Saldana in Hollywood, California.

What: A strapless ivory gown by Oscar De La Renta with a narrow diamond collar and cocktail ring by Tiffany & Co.

Why: It's not everyone who can wrap a bedsheet around their body, call it a day, and still look ready for the cameras. Fanning glams up an understated Oscar De La Renta column gown with chunky, decadent accessories. A diamond necklace coils around her neck, complementing the gentle round neckline of the gown; a large cocktail ring adorns one hand. She goes minimalist on the makeup, opting for a nude lip, understated eyes, and a simple center part. We didn't know so little effort could make such an exceptional look, but Fanning is steadily proving you don't need awards season to win big on the red carpet.
