firefighter
Costume ideas for firefighters who work to protect people’s lives.
How about creating cool outfits that match kids giving their all in various events? For the helmet, line a bowl-shaped container with aluminum foil and attach a colored plastic bag.
Make the body cape by using a colored plastic bag fitted with a zipper.
Use silver or gray colored plastic bags to represent firefighters.
You can also expand the concept with ideas like a game where kids put out illustrations of flames.
Original T-shirt

How about making original T-shirts for the sports day? They’re great as uniforms for the kids and as cheering gear for parents.
Add unique illustrations or your class motto, and you’ll have a wonderful design everyone will remember.
They’re also attractive because you can make them at low cost.
Perfect for boosting team spirit and enjoying the sense of unity on sports day.
The message on your custom-made T-shirts will surely stay in participants’ hearts.
The process of creating them together is fun too, so give it a try!
tulle skirt

The soft, springy tulle fabric adds visible volume, making it perfect for dance costumes at school sports days! If you’re making a skirt, I recommend using soft tulle, which is easy even for beginners to handle.
The method is simple: prepare several rectangular pieces of tulle cut to fit the body, then tie them onto an elastic waistband.
Threading a large ribbon around the waist or playing with color combinations will give it a lovely finish.
A romantic tulle skirt will come in handy not only for sports days but also for events like Halloween and Christmas.

Alice-style outfit

Refreshing colors are perfect for a sports day! Here are some costume ideas inspired by Alice.
The blue dress with a white apron is a popular outfit that many children want to wear at least once.
This time, let’s make an Alice-like costume using colored plastic bags.
It’s also great for events themed around a fantasy world.
With Alice’s “free-spirited creativity” and “adventurous spirit” on their side, we hope children can take part in sports day with confidence and joy.
Be sure to give it a try on this occasion!
ninja

Lightweight and easy to move in! Here are some ninja costume ideas.
When you think of ninjas, they’re cool and something kids admire, right? These ideas are perfect for anyone who thinks making a ninja outfit seems difficult.
By using colored plastic bags, you can create a lightweight, flexible ninja costume with simple steps! Another nice point is that you can customize the neck decoration tape—from metallic styles to masking tape.
Put on your handmade costume and dance like a true ninja!
Momotaro
Costume ideas themed on Momotaro, a beloved traditional folktale.
Create them together with the loyal companions—the dog, monkey, and pheasant.
Make hooded headpieces for Momotaro and the animals, and use vests to evoke traditional Japanese clothing.
Add parts that represent small items like peaches and millet dumplings to complete the costumes.
It’s also great to try activities themed around Momotaro, such as songs and dances.
This idea combines cool, Japan-inspired outfits with the kids’ cute looks.
We also recommend incorporating original games tailored to the story.
cheer
Don’t you feel energized just by looking at cheer dance outfits with their all-American vibe? How about bringing that cheer style to your sports day? Try an easy DIY using the classic red, white, and blue cheer colors! If you want something simple, felt is the way to go.
Just cut the skirt pieces with scissors and attach them with cellophane tape or fabric tape.
With felt, you don’t need to finish the fabric edges, so it’s perfect when you’re short on prep time.
And not just the skirt—adding a ribbon to tie around the neck would be adorable, too.
