It's fair to say that Harrier took this year's Met Gala theme seriously. Harrier wore a beautiful black custom H&M gown made in collaboration with Victor Glemaud. Though she nailed the Gilded Glamour theme with the corset bodice and Gilded Age-esque finger waved styled hair, Harrier took it a step further when she shared that, though completely unseen to the public, there is actually an original petticoat from the Gilded Age era underneath the gown of her dress.
