The clip opens up with an amazing photo of Sevigny and Kate Moss backstage at a Miu Miu show. BEST. There’s also a look at a gorgeous Proenza Schouler dress she wore to the Met Gala, which she promptly ripped while dancing. We also learned she’s addicted to black boots, denim, and old t-shirts. And FYI, her best Halloween costume was Joan of Arc.
