THE POP PRINCESS SET IT OFF LAST NIGHT, OPENING HER WORLD TOUR WITH AN INCREDIBLE AMOUNT OF COSTUME CHANGES—AND SHE'S JUST GETTING STARTED
May 8th, 2014. Last night, Katy Perry started off her Prismatic tour in Belfast, Northern Ireland. Involved in each part of the show from stagelights to sequins, Perry apparently didn't think leaking her setlist would take away from the action-packed performances. Costume sketches have been trickling out until now, too, and we have those, plus extra images from the designers themselves to give you an idea of the kinds of "Fireworks" you'll see her set off all over the globe. The world-tour wardrobe is filled with custom designer ware, from both the major leagues and fresh faces of fashion (see the slideshow above).
