The "Therefore I Am" singer is known for her baggy ensembles, but donned figure-hugging old Hollywood-inspired corsets in the photoshoot for the magazine.
"I've literally never done anything in this realm at all," Eilish said of the look, which she came up with herself. "Y'know, besides when I'm alone and s**t."
In one photo, Elish wore a corset and a custom trench coat by Burberry with nude suspenders, giving fans a peek of the tattoo across her thigh and stomach, which has never been seen before.
In another photo, she wore an Alexander McQueen corset dress with Atsuko Kudo stockings and a suspender belt.
Eilish also stunned in a black Mugler catsuit and corset. Although corsets are back in fashion, Eilish admitted that she was drawn to them because "I hate my stomach, and that's why."
Why would Eilish model a corset if she constantly preaches "body positivity"? "My thing is that I can do whatever I want," she said. "It's all about what makes you feel good. If you want to get surgery, go get surgery. If you want to wear a dress that somebody thinks that you look too big wearing, f**k it — if you feel like you look good, you look good."
Eilish donned baggy clothing in her early career and previously said it was so people do not sexualize her, but told Dazed last year it was because she was insecure about her body. Now, Eilish told Vogue that "showing your body and showing your skin — or not — should not take away any respect from you."
The photoshoot debuted after Eilish's new single, "Your Power," dropped; the song is "about taking that power back, showing it off and not taking advantage with it. I'm not letting myself be owned anymore."
"You're going to complain about being taken advantage of as a minor, but then you're going to show your boobs?" Eilish said of the potential criticism. "Yes I am, motherf**ker! I'm going to because there's no excuse."
Of the new song, she explained, "It's an open letter to people who take advantage — mostly men. I would like people to listen to me. And not just try to figure out who I'm talking about, because it's not about that. It's really not at all about one person."
After the new pictures hit the internet, the singer took to social media to proudly share them. "I love these pictures and i loved doing this shoot. do whatever you want whenever you want. f**k everything else," Eilish gushed.
However, one thing Eilish did not confirm to British Vogue was whether or not she has a horse after her brother Finneas previously said if she wasn't a singer she would be an equestrian. "That’s a whole part of my life that I’m not interested in anybody having any info on," Eilish told the outlet.
