Roar! Best Katy Perry Halloween Costumes Ideas to Rock

Spread the love

You know these looks! These are some of the most iconic Katy Perry looks from over the years. You can wear one of these Katy Perry Halloween costumes ideas literally every year for years, with no repeats. We love an over the top queen!

katy perry halloween costumes ideas

This post is a list of the best Katy Perry Halloween costumes ideas to rock this year and beyond! It’ll give you tons of costume inspo pulled straight from some of her most iconic looks.

Katy’s music videos are legendary for the outfits as much as the music. When it comes to halloween costumes, we are so here for the glitter, the wigs, the elaborate costumes, the whole thing. We LOVE it!

2025 Costume Idea – Katy the Astronaut?

I’ve been a fan of her music forever — “California Gurls,” “E.T.,” “Teenage Dream,” “Last Friday Night” — all total bops. (My all-time favorite though? “Wide Awake.” I’m obsessed with it.) Katy, Taylor Swift, Britney Spears – songs from these divas immediately take me back to certain places and times in my life.

Katy Perry music videos are basically costume catalogs, and between her VMA performances, Super Bowl halftime show, and appearances at events like the Met Gala, it’s almost impossible to pick just one favorite. I mean, how do you choose between the iconic blue wig, the cotton candy clouds, and the time she dressed like a giant flaming Cheeto?

We featured a few of her most memorable looks, so if you’re looking for a katy perry halloween costume idea that’s bold, instantly recognizable, and a little bit wild — you’re in the right place. Like Katy once said: “You’re gonna hear me roar.”

Slowestuff Halloween Section

Halloween costume ideas

We LOVE Halloween, so we definitely have a whole section of the blog dedicated to it!

This post focuses on great Katy Perry costume ideas, but we have lots of costume inspiration. Ideas for people with glasses (men & women), Father & Son or Mother & Son costume ideas, costumes for pets, and babies – really something for everyone who wants to get dressed up and have fun on Halloween.

It’s not just costumes though! We also love all the decorations we see in homes and yards, so we have great home decor ideas too.

Halloween extends into our scrapbooking section, with several posts featuring our favorite Halloween layouts. And is there a better reading season than spooky season?? We have plenty of horror book recs and our favorite enchanting witchy books that are perfect to get you in the spirit.

Katy Perry Looks

Katy perry halloween costume ideas
ICONIC! One of the legendary outfits from California Girls video.

One of the things we love about Katy is how she is down to dress over the top all the time! Not even for just performances, but even for things like walking the Hollywood Walk of Fame where she wore a scorching red dress, or bringing a hilarious twist to some Sesame Street drama (that Elmo shirt!!), Katy’s outfits are always bangers!

I credit a lot of the costumes on here, and please do go and visit those pages! A lot of them walk you through some DIY that they did to make the costumes. If you’ve got a little fabric paint, hot glue, pipe cleaners and time, you can totally bring your own katy perry costume ideas to life.

If high fashion is more your thing, recreate one of her jaw-dropping Met Gala looks — like that dramatic red ensemble inspired by Rei Kawakubo that turned heads and broke the internet. Or throw it back to a VMA performance where she dazzled in outrageous bright colors, glitter boots, and the kind of creative outfits only Katy could pull off.

She’s taken home the Video of the Year Award, walked red carpets in a stunning Valentino gown, and even pulled off a teeny-tiny minidress like it was no big deal.

Honestly, choosing just one best look is almost impossible — so maybe do a costume change halfway through the night?


Roar! Best Katy Perry Halloween Costumes Ideas to Rock

SuperBowl Halftime with Left Shark

This is one of our favorites because you have to know the “inside joke” about left shark from that performance. Plus, it is a perfect couples costume idea!

You can totally have a great solo costume with the absolutely perfect prop of a stuffed shark!

This is also an amazingly perfect couples costume. We love all the different sharks here!

Re-Create The Look!

It’s actually really hard to find this beachball dress that Katy wore during the Super Bowl show. There are shops that will make it custom for you, so definitely go search that up, but just be ready to spend a little bit more than a typical price point.

I did find this one listed on Etsy for a very reasonable price!

For you DIY’ers out there, here is a link to a tutorial on how to make it!

I found lots of options for left shark tho!

Dig through your Christmas decorations to find some candy cane themed things and it is perfect for this one. Stick on some red gloves and grab the mic and you are set! If you don’t have dark hair, you can always top it with a wig for the perfect finishing touch.

Niche Katy Perry

I stumbled upon an instagram page that has soooo many amazing Katy Perry costumes – check out the costume designer rhinestonedbyregan for tons of inspiration. These next three looks are all by her. Aren’t they AMAZING?!!

This one makes me laugh. She did a costume of Katy Perry getting slimed at the Kids Choice Awards! LOL!


Roar

Katy’s Roar look is probably one of the easiest to make as a DIY costume.
