When Billie Eilish released her Barbie movie soundtrack song “What Was I Made For?” last week, it came alongside a video, which Eilish directed herself. The single-shot video sees Eilish opening a box full of miniature, doll-sized outfits, which turn out to be representations of some classic looks she’s worn throughout her career. Now, Eilish has pulled back the curtain on the making of the visual with a new behind-the-scenes video.
