Maya Hawke says her 'Stranger Things' premiere dress was full of hidden details about the show's new season

• Maya Hawke attended the "Stranger Things" season four premiere in New York City on Saturday.
• She wore a bold Christian Dior dress that had hidden details about the show's new episodes.

Season four of Netflix's "Stranger Things" is set to premiere next week, but one of the show's actors shared hints at the upcoming episodes as early as last Saturday.

Maya Hawke attended the "Stranger Things" season four premiere in New York City on Saturday, and wore a black Christian Dior gown on the red carpet. The dress, which had a corset bodice and pleated skirt, was decorated with silk embroidery shaped like everything from bees to stars.

As Hawke told Elle, the designs actually hinted at new "Stranger Things" characters — specifically, a new kind of demogorgon monster called demobats.

"They're opening the lore of what all of this is about and there is a dark menacing force named Vecna who is like the devil," Hawke told the publication. "The dress has 'diablo' on it, and I feel like it has the spirit of Vecna as well as the ancillary monsters throughout."

The gown was originally shown on a Christian Dior runway, though a new version was made specifically for Hawke.

"There is a lot of symbolism through the dress that relates to the show. I really love the show," she said. "After working on it for almost three years, I wanted to show that through my look. Dior was so supportive in helping remake a dress from a past season for this. I wanted to go all out with black and red nails."

And as it turns out, her red-carpet appearance was also a family affair. She told Elle that she got dressed at her mom Uma Thurman's house, and took photos with her younger sister who "touched up" Hawke's hairstyle.

"My mom gave me some advice on how to stand," she said about preparing for the red carpet.
