Beanie Feldstein Wore Her Prom Dress on the Screen Actors Guild 2018 Awards Red Carpet

Sunday night’s 2018 Screen Actors Guild Awards was populated by actresses in gowns that were probably designed to be worn just once for this event. One dress, however, came from a more unexpected source. Lady Bird star Beanie Feldstein decided to forgo the bespoke evening gown in favor of her high school prom dress.

“I put it on and it fit, surprisingly maybe better than it did in high school,” she told The Cut. “I looked at myself, and I was like, WHAT!? and my mom and her best friend were just laughing so hard, like, ‘You have to wear it! There’s just no other dress that would be better.’”

Indeed, Beanie is rocking the elegant black Kay Unger gown on the red carpet, where it does not look out of place among, say, costar Saoirse Ronan’s pink Louis Vuitton gown or Danielle Brooks’s show-stopping sequined black-and-blood-red Marc Bouwer ensemble.

Beanie told The Cut that the prom dress was doubly fitting for the Screen Actors Guild Awards — the first time she’ll attend an awards show as a nominee (Lady Bird received a nomination for Outstanding Performance by a Cast in a Motion Picture) — due to her character Julie’s storyline in the film. “It’s just a gorgeous dress, and I love how my character’s story ends at the prom,” she continued. “So like, for the first time I’m going to an awards show as a nominee with the cast, it’s like, ‘You gotta wear your prom dress, girl, and honor Julie.’”
