It's the fashion event of the year -- the Met Gala!

Check out the fab fashions and the fierce ensembles of the 2016 Metropolitan Museum of Art’s Annual Costume Institute Benefit. This year the theme is "Manus x Machina: Fashion in an Age of Technology."

According to Vogue, the theme is intended to embrace the blurred lines between handmade haute couture and machine-made fashion.

A slew of celebs will be attending fashion's most creative night -- and of course all eyes will be on Taylor Swift, who is co-hosting this year's bash.

Interesting enough, Katy Perry (Tay's arch nemesis is also in attendance). At a CoverGirl event on Sunday night, Katy talked about the enormous size of her dress. "I'm wearing a really large thing tomorrow, which will be very difficult to use the restroom in. I might just wear a diaper. I don't really care. I am just going to be looking around for people to help me to the restroom."

She added, "I'll feel like one of those brides or something, but there's a lot going on with the dress."
