Billie Eilish is known for wearing bright and baggy clothes, and she's said before that it's so people "can't have an opinion" about her body.
In an interview with Vogue Australia, she elaborates on her point, and jokes that she likes to wear clothes that are “800 sizes bigger" than she is.
“It kind of gives nobody the opportunity to judge what your body looks like,” Billie said. “Anything you look at, you judge. That’s just how we all work, that’s how human beings work.”
