Oscar winner Lupita Nyong’o was a vision on the red carpet at the 2018 SAG Awards.

The actress, who won a SAG Award in 2014 for her performance in 12 Years a Slave, stole the spotlight ahead of the ceremony in a strapless and glimmering silver Ralph & Russo column dress with a sheer black feather-bearing train.

Nyong’o, 34, donned a sophisticated close-cropped cut and a dark metallic mauve lip. She paired the minimal makeup look with diamond drop earrings and a set of silver rings.

During the show itself, Lupita and Brie Larson presented an award—and announced that SAG has created a new code of conduct for movie sets.

"It gives us joy to celebrate portrayals that show human nature with all its imperfections, and to do so with a union whose job it is to protect actors as they do that job," Nyong’o said.

"Which is why we're so excited to say that—with collaborations with Time's Up and your union members here in this room—there will be a new code of conduct to ensure that there is safety on set," Larson said. "So we can continue to be vulnerable, continue to be emphatic, and do the strong and great performances that we've seen brief glimpse of here tonight."

Gabrielle Carteris, president of SAG-AFTRA, gave a statement regarding the code to InStyle:

"We are working with our members including several who are active in the Time's Up campaign to develop a Code of Conduct that provides clear safety guidance to performers in the work environment and in the social environments attached to work like auditions, wrap parties, festivals, etc., where harassment frequently occurs.

"We are working very thoughtfully in developing the Code of Conduct so that it is as effective as possible in protecting our members. We are drafting now and will distribute it when complete.”
