“I never want the world to know everything about me” Billie Eilish explains in a new ad for Calvin Klein. “That’s why I wear big, baggy clothes. Nobody can have an opinion because that haven’t seen what’s underneath.”

After listing off a string of proposed guesses about her body, Eilish brings it into focus. “Nobody can say any of that, because they don’t know.”

Last year, Eilish shared a similar message during an interview with NME. “I’ve spoken a lot to female artists about this, because if you’re not a female artist you probably don’t think about this” she said. “If I was a guy and I was wearing these baggy clothes, nobody would bat an eye. There’s people out there saying, ‘Dress like a girl for once! Wear tight clothes you’d be much prettier and your career would be so much better!’ No it wouldn’t. It literally would not.”’
