Last night (May 7) Katy Perry launched the ‘Prismatic World Tour’ in Belfast, Ireland, in an incredible display of colorful costumes, complicated choreography, and seriously impressive stage setups.

The ‘Dark Horse’ singer kicked off her seven-month long world tour with a visually stunning performance. She made nine costume changes, all of which fell into the seven divisions of the show that were revealed in a set list photo Katy Instagrammed earlier this week. Every theme fits with the 'Prism' star's image, ranging from Egyptian to Cat-oure to Hyper Neon.

But seriously — nine costume changes. Can you imagine?!

Each costume is worth the hassle, as there isn’t a single piece that doesn’t look carefully and thoughtfully designed to work with both Katy’s body and the stage design.

Check out a few of her costumes below. They’re unreal!
