Chanel #3 is lowkey LIFE. Billie described her as "a lowkey individual" in her video, and I think that's pretty accurate. She slays in all aspects-- her outfits are kinda the best, but we don't see them as much as Chanel Oberlin's, and her dialogue is hysterical but it flies by so quick and is really just... lowkey.
I love her, but with characters like Hester & Chanel & Chad around she kinda fades into the background despite how much she slays.
