Troian Bellisario Almost Wore Lauren Bacall's Nightgown in 'Pretty Little Liars' Noir Episode

We all have old Hollywood stars that we admire — it might be Audrey Hepburn, or Rita Hayworth, or maybe it’s Grace Kelly.

For Troian Bellisario though, she might have had a little freak out after getting to wear Lauren Bacall‘s nightgown in Pretty Little Liars‘ Noir episode.

“When we were doing the film noir episode, because Warner Bros. has been a studio for a long time, they pulled a lot of costumes from the ’40s,” she revealed in a new interview. “I got to try on Lauren Bacall’s nightgown from The Big Sleep.”

Troian adds, “It was so cool because Joe Dougherty, who wrote the noir episode, based Spencer’s character on Lauren Bacall. Toby was based on Humphrey Bogart�our whole scene together was supposed to be a Bacall-and-Bogart callback.”

Even though she tried it on, she didn’t get to wear it.

“It really upsets me, actually, that we didn’t end up using that nightgown. I mean, how could you not use Lauren Bacall’s actual nightgown?!”
