If you know anything about Billie Eilish then you know that she chooses to wear baggy clothes because she doesn't want people to know what her body looks like so that they can make comments about it! So she does what she can to shift the mentality over body shaming!
"If I wear what is comfortable, I am not a woman. If I shed the layers, I’m a slut. Though you’ve never seen my body, you still judge it and judge me for it. Why?"
"We make assumptions about people based on their size. We decide who they are, we decide what they’re worth. If I wear more, If I wear less, who decides what that makes me? What that means? If my value based only on your perception? Or is your opinion of me not my responsibility?"
Check out the video she aired during her show in Miami! Obviously this stunned fans since it's not something they're use to seeing Billie do.
