Katy Perry's 9 Most Glorious 'Prismatic' Costumes

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.

"Nobody reps this place harder than I do," she told the California crowd. But she also repped Cleopatra during "Dark Horse." Not pictured: mummified female backup dancers tweaking with comically padded assets.

The glorious Kitty Purry vignette included animated cats shopping on Rodeo Drive, getting acupuncture and hitting the "Pawtages Theater" for a show - all set to Snoop Dogg's "Gin and Juice." A tap dancer emerged on stage dressed in a full cat suit (not the sexy kind, but the furry kind with ears) while other cat-dressed dancers played on giant scratching posts. Perry emerged atop a giant ball of yarn to perform a swing-y version of "Hot N Cold." Later, she hit the catwalk with "Vogue" and performed the "milk bucket challenge." (Spoiler alert: She was doused in glitter from a giant milk bowl - not real milk. Thankfully.)

"I just had to change my outfit because I know how people judge in L.A.,:" Perry purred on her next wardrobe switch. Referring to her new 'do, she added, "We do live in a city of excess… why have one color of the rainbow when you can have all of them?"

Perry was "Walking on Air" in this smiley get-up, preceded by late-'80s/early-'90s DJ mashup that included "Pump Up the Jam," "Finally" and more.

Fittingly, yin and yang for "It Takes Two."

Things got a little wild (and a lot neon) in the homestretch, with "This Is How We Do," "Last Friday Night," "Teenage Dream" and "California Gurls."

Before busting out the big balloons, Perry called up an audience member for a "Birthday" serenade. Perry will celebrate her own 30th birthday on October 25.

C'mon let your colors burst.
