The 26-year-old Vinyl star was accompanied by the designer of her Erdem gown at the annual event.
Juno took to Instagram to post a photo of the two before they left for the gala, writing, “Best prom date ever.”
Also in attendance was fashion blogger Tavi Gevinson, who opted for a shorter dress.
FYI: Juno is wearing Erdem. Tavi is wearing Coach.
