Jamie Lee Curtis is paying tribute to her mother.
Curtis honored her mother by copying one of Leigh's looks from the movie.
The actress donned a powder blue button-up dress with black heels and a matching bag. To complete the look, Curtis wore a short blonde wig and carried a bloodied shower curtain.
Ahead of the movie premiere, the actress shared a photo of herself in costume on Instagram.
"Honoring my mother in ALL her gory...I meant glory!" she joked in the caption. "PREMIERE PARTY TIME!"
Several celebrities expressed their adoration for the tribute look.
"You’re a flipping genius!" Jennifer Grey wrote.
"This is the greatest thing I’ve ever seen," added Amy Landecker.
Mariel Hemingway wrote: "So so so great."
"I am honoring my beautiful late mama, Janet Leigh, but... it's a little more meta than that," Curtis told Entertainment Tonight at the premiere. "I am actually going as Scarlett Johansson as Janet Leigh in the movie ‘Hitchcock.’ So it's meta because we never knew what color Janet Leigh's dress was because it was a black-and-white movie."
Curtis said that "Hitchcock" taught her that the dress was actually blue and added that she whipped up the bloody curtain so as not to be confused for a 1950's housewife.
"It's actually quite sticky and it stains," the actress said of the fake blood. "Here's my secret for those who are interested: Dish soap. Like a good dish soap will actually get out fake blood."
