Katy Perry
is ready to "Roar!"

The singer kicked off her Prismatic World Tour in Belfast, Northern Ireland on Wednesday night, and she sported some crazy couture costumes on the stage.

The brunette beauty donned nine different show-stopping ensembles, including a pink skintight latex bodysuit, a smiley face bra with peace sign-covered leggings, a Kaleidoscope Brodè fringe dress and more!

According to InStyle, the current lineup of Katy's tour designers includes Roberto Cavalli, Valentino, Moschino, Nicholas Jebran, The Blonds, Todd Thomas, Discount Universe and Fausto Pulisi.

The "Dark Horse" songstress took to Twitter to share her excitement after the show.

"Tonight was INSANE in all the best ways," she tweeted. "I have a feeling the light hit everyone! #ThePrismaticWorldTour."

Perry has another show in Belfast on Thursday night, followed by a series of shows in Europe throughout the month of May. She kicks off the U.S. leg of her tour on June 22 in Raleigh, North Carolina.
