An obsession with Billie Eilish and her style is practically required if you identify as Generation Z. But even if you’re don’t, there’s much to appreciate. The 18-year pop star was arguably the year’s biggest breakout musician—at least according to Google, who said Eilish was its top-trending pop star of 2019—and is recognizable not only for her signature sound, but also for her signature style characterized by bold, drastically oversized pieces that seems to meld classic hip-hop style with goth and skater influences. In May 2019, Eilish revealed in a Calvin Klein campaign that everything she puts on is deliberate; a method to deflect judgement of her body. “I never want the world to know everything about me,” she said. “I mean, that’s why I wear big, baggy clothes. Nobody can have an opinion because they haven’t seen what’s underneath. Nobody can be like, ‘Oh, she’s slim-thick, she’s not slim-thick, she’s got a flat ass, she’s got a fat ass. No one can say any of that because they don’t know.”

Eilish turned 18 in December 2019, an age she admits might be the catalyst for trying something new as far as her style goes. “I’m gonna be a woman. I wanna show my body,” Eilish told Elle magazine in October 2019. “What if I wanna make a video where I wanna look desirable? Not a porno! But I know it would be a huge thing. I know people will say, ‘I’ve lost all respect for her.’”
