When it comes to Katy Perry's Prismatic World Tour, the sights are just as important as the sounds.
Perry puts on a candy-colored spectacle (and we mean spectacle) fit for pop royalty. She runs, she jumps, she flies, she screams and she sings. In between, she changes.
The 29-year-old and her dancers powered through two-and-a-half hours of hits during her hometown stint in Los Angeles, with more than a handful of costume changes -- each one more jaw-dropping than the next.
Kicking things off with a trifecta of hits ("Roar," "Part of Me" and "Wide Awake") Perry rocked a skirt and crop top fit for a rave. When the lights dimmed, she lit up like a glow stick.
