We're mere hours away from fashion's biggest and most fabulous night of the year: the 2018 Met Gala.

Today (May 7), New York City will play host to a surplus of celebrities as stars from all corners of the industry—from fashion to music to Hollywood's elite—gather for the annual soiree at the Metropolitan Museum of Art.

This year's theme, "Heavenly Bodies: Fashion & The Catholic Imagination," will see celebrities like Katy Perry, Ariana Grande, Troye Sivan and more explore the space between couture and Christianity.
