But Jared Leto brought an accessory that was truly one of a kind: his own head.
The 47-year-old actor and 30 Seconds to Mars frontman took the event's "Camp: Notes on Fashion" theme to a new level with a fashion statement that was more Madame Tussauds than Mugler or Marc Jacobs.
The item was inspired by Gucci's Fall 2018 show, during which models strutted the runway with similar replicas of their own heads. Leto also wore a crimson, jewel-encrusted gown from the fashion house.
The likeness is striking; the re-creation perfectly captures the "My So-Called Life" star's deep brown mane, scruffy beard and, of course, the intense blue eyes we remember from his Jordan Catalano days. (Angela Chase once said, “He's always closing his eyes, like it hurts to look at things,” but we assume the Gucci head won't share that habit.)
