Anya Taylor-Joy landed herself in hot water with her fans.

The actress attended the New York premiere of "Dune: Part 2" in a gold bodycon dress, with a layer of black tulle on top. In an Instagram post recapping the night, Taylor-Joy posted a black-and-white photo of herself in the corset she was wearing underneath, showing her followers how slim her frame is.

Commenters immediately began voicing their opinions about the actress' decision to share the photo, with some calling it toxic, and others saying there's nothing wrong with it.

"Do you realize how corsets are hurtful for women's health and should not be promoted," one person wrote, with another adding, "Can we not normalize starvation?"

"Rough. Expected better from you tbh. Thinness isn't chic," another follower commented. "Nothing to be proud of & sets a poor example for young girls," wrote another.

"This is really triggering to a lot of people :(," one comment read.

While there were many negative comments under the post, there were some who came to the actress' defense, with one fan writing, "Sensing A LOT of pettiness and jealousy in these comments."

Some fans called for everyone to "let a woman be free" and realize "she’s not promoting anything" by posting a photo of herself in an outfit. "If she likes it good, if you don’t, it’s perfectly fine," they concluded.

"Everyone wants more freedom for women and for them to be more empowered, and when she dresses the way she wants all of a sudden all the women are against her. Check your hypocrisy a little bit," one defender wrote.

Taylor-Joy first came to prominence when she starred in the 2015 horror film "The Witch." She went on to play Beth Harmon in the Netflix miniseries "The Queen's Gambit." She has since appeared in "The Menu," "Last Night in Soho," "Amsterdam," and most recently, "Dune: Part 2."

The director of "Dune: Part 2," Denis Villeneuve, wanted to keep Taylor-Joy's involvement in the movie a secret for as long as possible, revealing her participation in the film on the red carpet at its premiere in London, when she was seen posing with the rest of the cast.

"I think that Hollywood is the most gossipy town on earth and I wanted, as an experiment, to see how long we could keep a secret," Villeneuve told The Hollywood Reporter in February. "We did it. It was a special unit. We went to Africa to shoot with Anya under super-secrecy. I just loved the idea to keep something a surprise for the audience until the very end; it was like a gift I wanted to keep for the fans."
