30+ DIY Halloween Costume Ideas for the Whole Family!

This year, I’d like to attempt to make my Halloween costume…instead of just buying it from a store. My mom would make our costumes when we were kids, and we absolutely loved them! (But if you like buying your costumes, check out this post featuring funny Halloween costumes you can buy online.)

I’m the princess wearing the hat below. I wore this costume my mom made 3 years in a row before I switched to another variation of a princess costume! (My little brother is the cowboy on the far end, and the other princess and cowboy are my cousins! Halloween was so much fun for us!)

An older film photo of four children dressed up for Halloween. Two little girls on the left are dressed up as princesses, and two little boys on the right are dressed up as cowboys.

I’ve been out of the Halloween costume game for a few years now, though. So, I enlisted the help of fellow bloggers who have some AMAZING DIY Halloween costumes for the whole family – even your pets. There are SO many good ones for your kiddos as well! I hope you love their ideas as much as I do!

Note: Many of these DIY costumes will be much easier to do if you have a Cricut, hot glue gun, and your own sewing machine.

DIY Family Halloween Costume Ideas

Where’s Waldo Costume for a Family

A family of three - mom, dad, and baby - dressed as Where's Waldo in red and white striped shirts, jeans, and red and white hats.

Most of the pieces for this cute Where’s Waldo Family Costume are items you may already have in your wardrobe, as it mainly consists of comfortable everyday clothing (like striped shirts & beanies)!

Firefighter-Themed Halloween Costume for the Family

A young child dressed as a firefighter plays in the back of a wagon, spraying a woman dressed as fire with a "firehose".

A toddler sits in a wagon dressed as a cute little cow for Halloween. She's wearing a black-spotted onesie, white tulle skirt, and a cow ears headband with a white bow.

How cute is this firefighter-themed costume for the family?! This idea is from blogging friend Arianny of Prep & Shine – we actually met when we were both in Jamaica for last year’s Sandals Resorts press trip!

In-N-Out Burger Group Halloween Costume

A family of four - mom, dad, and two young children- stand outside of an In-N-Out restaurant, dressed in DIY Halloween Costumes. The dad and little boy are dressed as fast food workers, the mom wears a dress that looks like a burger, and the little girl is dressed in a French fries costume.

While we don’t have any In-N-Outs by us, I still can’t get enough of this DIY In-N-Out Burger family costume by Lovely Indeed!

DIY Halloween Costume Ideas for Adults

DIY Mermaid Bra + Chiffon Skirt

A handmaid mermaid bra for an adult Halloween costume. The bra is decorated with seashells and fish netting.

A woman models a long, flowy turquoise maxi skirt, which would be perfect for a mermaid Halloween costume.

Making a mermaid bra is not as complicated as I thought it was! Natasha does a great job of breaking down the process. Plus, she is also sharing how to make your own DIY chiffon skirt to go with your mermaid bra! (Or buy the skirt above.)

DIY Sexy Steampunk Costumes

A couple dressed in steampunk-themed Halloween costumes. The man wears a black velvet suit, red vest, and top had. The woman wears a black corset over a white off-the-shoulder blouse and blue satin skirt.

Trina breaks down how to make these awesome DIY Sexy Steampunk Costumes. I absolutely LOVE the hat she created!

Easy DIY Unicorn Costume

A woman poses in front of Cinderella's castle in Disney, and she's wearing a DIY unicorn costume made from a rainbow skirt, white top, pastel colored wig, and a unicorn horn headband.

This super cute DIY Unicorn Costume is great for adults but could just as easily work for a kiddo!

DIY Bo Peep with Cricut

A woman is dressed a Bo Peep, wearing a DIY'd shirt created with a Cricut. She poses with a little boy dressed as Buzz Lightyear in front of a pastel pink wall.

Are there any Toy Story 4 fans out there? This adorable DIY Bo Peep Costume is for you! Plus, you could just as easily make this a family costume (or a couple’s costume with a Buzz Lightyear costume).

This is Miss Muffet & Her Spider costume idea is seriously the cutest thing ever!

Headless Costume

A young boy is dressed in a brilliant DIY Halloween costume. He looks headless, wearing a long beige trench coat and brown cloves, his head floating in the middle.

This wins, hands down, for the most creative kiddo Halloween costume on this list! This DIY Headless Costume is also completed by putting a Cheese Puff jar over his head to make it look as though he’s carrying his head in a jar – it’s awesome!

Steve Irwin Costume for Kids

A little girl is dressed like Steve Irwin, in a khaki outfit, holding a stuffed croccodile toy.

I also think this Steve Irwin costume is genius! You can use khaki clothes from your kiddo’s closet and have them carry around a stuffed crocodile… and you’ll be good to go!

DIY Bat & Butterfly Costume

Two kids pose on a sidewalk, dressed in all black as a bat and butterfly. The butterfly costume has bright yellow wing.

Minecraft Creeper Costume

A little boy is dressed as a Minecraft Creeper, a DIY halloween costume made from squares of green and black papers, meant to look pixilated.

I had to look at that photo for a second before I could spot the Minecraft Creeper, haha! Minecraft is a popular video game and this DIY Minecraft Creeper Costume is not only fun to make, but it’s also comfy for the kids to wear!

DIY Pirate Costume for Kids

A child's pirate costume - red and white striped shirt, black vest, pirate's hat, and eye patch - all laid out on a white surface. A little pouch of "loot" (chocolate gold coins) sits next to the clothing.

This DIY Pirate Costume also comes with a free pattern! My brother was a big fan of pirate costumes growing up as well!

This Halloween Bride Costume is fun to make, plus it won’t break the bank!

DIY Monsters Inc Shirts

A cute little boy walks down the stressed dressed as Batman, holding a stuffed bunny toy.

Using some old clothes in your home, you can easily create this Upcycled Batman Costume!
