Designers Dish on Katy Perry's Outrageous Tour Outfits

Katy Perry's 'Prismatic World Tour' costumes are "bigger and better" than ever before.

The 'Roar' singer is known for putting on a stellar show, so her team made sure to top the candy-inspired looks from her 2011 'California Dreams' tour with a collection of futuristic and outlandish looks.

Katy and her loyal stylist Johnny Wujek enlisted a team of leading designers to bring their vision to life, including Moschino's Jeremy Scott, Roberto Cavalli and Todd Thomas.

Johnny explained to Billboard.com: "We went into this tour knowing the costumes had to be bigger and better than the last."

The show is divided into themed sections called Prismatic, Egyptian, Cat-Oure, Acoustic, Throw Back and Hyper Neon, with each part comprising a distinct style and pop culture references.

Cavalli created the sparkling holographic skirt and crop-top combination that Katy wore to open the show, backed by spear-wielding soldiers dabbed in luminous paint. 

He said: "It needed to allow her to dance and sing without limitations. I wanted to make something extremely unique, an authentic showstopper."

Meanwhile, Moschino's creative director Jeremy Scott re-imagined the label's smiley face motif for the 29-year-old star by dressing her in peace-sign leggings, a yellow bustier and matching leather jacket.

The designer revealed: "For Katy, I had to deal with hiding rigging mechanisms for her costume changes and make buckles look normal close-up with just a splash of Velcro."

Katy kicked off her ambitious tour on May 7 and it concludes in December 2014.
