RALEIGH, North Carolina -- You know when you were a kid and you went to the museum and you didn't understand the concept of a museum so you thought it was a shop and you wanted to buy all the shiny Egyptian artifacts and iconic paintings and take them home? And then, when your parents told you that you couldn't, you cried and cried and cried?

Well, seeing Katy Perry's Prismatic World Tour is kind of like going to a museum. From her giant ride-on "Dark Horse" to the butterfly crown that flapped its wings, Perry had a lot of stuff there on stage that I ardently wanted. Luckily, said tour had the equivalent of a museum store for all of us who wanted to look and touch and own: the merch stand.

Check out all the stuff that made my fingers itchy below:

The Prismatic merch stand was a glittering treasure trove of objets d'art

Like this T-shirt that really drove home the 'big balloons' innuendo in 'Birthday'

And this way cool vintage 'Roar' poster

And this slowly undulating jungle beast

You could also cop Katy's 'Drive'-esque 'Roar' jacket and some seriously '90s smiley gear

And somewhere there was a holographic backpack but not in plain site -- likely because its beauty was blinding

I did get to actually touch this amazing Prism necklace because I purchased it and wore it to bed and dreamt of rainbows and unicorns

All show-goers were also given a pair of 3D glasses for free!

Which allowed us to see Katy's 'Firework' finale wreathed in rainbows...

... And take selfies alone at Katy Perry concerts that we'll treasure for years to come
