Easy! Costume ideas made with colored plastic bags
At kindergarten and school events where children perform plays, dances, and songs, many kids and parents look forward to wearing wonderful costumes.
But sewing costumes completely from scratch can be a real challenge! So this time, we’re introducing costume ideas made from colored plastic bags.
Colored plastic bags come in a wide variety of colors, pair well with colored tape and ribbons, and are easy to shape just by cutting with scissors and sticking together with clear tape.
They’re also more cost-effective than fabric, which is a nice bonus.
Even if you’re not good at sewing, you can make adorable costumes easily by making the most of the shape of the bags.
Give it a try and create costumes that are perfect for the children.

Easy! Costume Ideas Using Colored Poly Bags (11–20)
dance costume
When it’s time to show off a dance at a sports day or other event, make a cool costume with colored plastic bags! Choose your favorite color, then cut a hole at the bottom of the bag for the neckline and openings on both sides for the armholes.
Add fabric tape in colors you like around the neckline and armholes for a stylish touch.
If you want to include graphics that match your dance or add your team name, foil origami paper and fabric tape are great options.
You can wear it as a sleeveless outfit, but if you want something cuter, try adding fluttery sleeves with gathers.
And yes, you won’t need a sewing machine, needle, or thread for the gathers either—just thread leftover plastic scraps through like string.
Customize it however you like with all kinds of creative touches!
ninja

Ninjas are traditional Japanese characters that are also popular overseas.
Let’s make costumes that match unique songs and dances! Place the prepared colored plastic bag with the bottom side facing up, and tape on the collar piece.
Next, use scissors to cut openings for the head and sleeves as well as shape the collar, and you’re done.
By adjusting the bag’s size and color, you can enjoy a variety of arrangements.
You might also create matching accessories like a hood for the head or shuriken.
These costumes suit a wide range of events, from sports day songs and dances to various other activities.
