Naomi Meredith for We Are Teachers
Pout Pout Fish
Materials:
Cardboard
Paint
Small paint roller and paintbrushes
Hot-glue gun
Scissors and/or cardboard cutter
Ribbon
Grab a large piece of cardboard and sketch out the shape of the fish body. Cut out the body, fins, and mouth to add a 3D effect. Roll on paint for larger sections, and use a paintbrush for the smaller details. Glue on ribbon.
Naomi’s tip: “You can wear any outfit with this. I wore a black T-shirt and leggings to let the fish be the star!”
Cut out a large yellow shield for the shirt and a smaller one for the hat, matching Dog Man’s. Hot-glue them onto black felt and cut them out to create the border. Finally, attach each shield onto the hat and shirt. Finish off the outfit with jeans and brown shoes.
Cut a large triangle out of the cardboard and paint it to look like a slice of pizza. Add felt or construction paper eyes and mouth, then attach it to your taco costume.
Naomi’s tip: “Turn this into a couple’s costume! If you’re dressing with a teammate, they can buy or make a large pizza slice costume instead.”
Individual Book Character Costume Ideas for Teachers
“Picture books are a great place to start, since you already know what the characters look like,” Naomi notes. “Dressing as characters from chapter books adds another level to creating the costume, since you are going off of the author’s description of the character.” Take a look at these creative book costumes from real educators for more inspiration.

Mo Willems’ Pigeon
Dressing like this beloved mischievous bird is easy with a clever knit cap. Attach the sign to a yardstick and stick it in your back pocket, and you’ll have a “caption” all day long!
We love the idea of being the coconut tree from this adored alphabet book! Add letters to a brown tunic and make yourself a headdress from construction paper.
Add big colorful buttons to a yellow shirt, add some cat ears, and you’ve got a Pete the Cat costume! If you can do the different-colored sneakers, even better.
Those fly eyes made from paper plates are totally cute and easy enough for any teacher to make. You can also make your own wings, or buy a pair to make the costume even easier.
If you really love putting effort into your costumes, take inspiration from this incredible Around the World in 80 Days costume. A giant beach ball balanced in a Hula-Hoop forms the “balloon,” and a pair of steampunk goggles adds an authentic touch.
This adorable penguin onesie costume is practically like wearing jammies to school. Just attach some question mark cutouts to transform it into the beloved book character.
Here’s another movie favorite that actually got his start in a book. Fortunately, you can pick up an easy all-in-one costume for the lovable green guy.
Need a team costume? Naomi knows that books are the perfect place to look. “What I love about book character costumes is you can dress up as one character by yourself—or if you have a whole group of people, you can add on more characters from the story to showcase the entire book!” she says. Here are some of our favorite team costumes featuring beloved book characters.

Party Animals
Mix animal costumes with birthday hats and noisemakers, and you’ve got the whole cast of characters from Tara Lazar’s adorable book!
Spread an environmental message with your teacher Halloween costume! “Unless someone like you cares a whole awful lot, nothing is going to get better. It’s not.”
This childhood favorite has been through dozens of adventures and looks a little different each time. That makes this a fantastic group costume, with each teacher dressing as their own version of Junie.
You can go all out with Pooh-themed costumes, but you don’t need to. These simple T-shirts and headbands get the idea across perfectly and are much more practical.
Pick up some big sheets of poster board and create your own costumes for the characters from the popular picture book series. These kids made their teacher dress up as the Bad Seed!
