Billie Eilish isn’t afraid to walk the red carpet wearing a head-to-toe monogram Gucci outfit or a Louis Vuitton face mask. But the “Bad Guy” singer does have one requirement when it comes to style: her clothes should be baggy.

In a 2019 Calvin Klein ad, the singer-songwriter said she wears oversized clothes because she doesn’t want anyone to have an opinion about her body. “Nobody can have an opinion because they haven’t seen what’s underneath, you know?” Eilish explained.

Eilish echoed the same sentiment in an August 2019 interview with Vogue Australia, adding that it’s also about not wanting the world to know everything about her.

“I want layers and layers and layers. I want to be mysterious,” she said. “You don’t know what’s underneath, you don’t know what’s on top.”

In honor of Eilish following her own style rules, here are some of the singer's best fashion moments so far.
