The 100th day of school is a super fun milestone and if you’re lucky, involves dressing up as part of the celebration. This is a one-time event, so how can you make your 100 days of school costume eco friendly, sustainable and as waste free as possible? Here are a bunch of ideas to keep it green while still having fun.
Kids, parents and teachers celebrate the 100 days of school (usually in August, but sometimes in July or September) for a few main reasons...
Academic Milestone - 100 days is an important point in school life, and a cute way to celebrate progress
Numeracy Skills - it's a great chance to practice counting skills
Sense of Accomplishment - Recognizing the 100th day of school helps encourages kids to keep learning
Classroom or Home-school Community - Celebrations can strengthen the sense of community between kids, education providers and parents
Creativity and Engagement - this usually involves needing to get creative and use your imaginations for costumes!
It's Fun - who doesn’t love a break from routine and throwing a party as part of the learning process
Dressing up has definitely become more of a tradition in recent years and costumes often revolve around the number 100 or showcase some kind of creativity related to the theme of 100 days of school.
Below are some great tips on keeping it low or zero waste and further on are some popular themes for costumes along with several ideas of how to do this without creating a bunch of unnecessary waste, AND reinforcing that sustainability can be fun too!
Key Tips on An Ecofriendly 100 Days of School Costume
Many of the costume ideas below work well with existing items you might already have, and for comfort or simplicity consider if you prefer to use an old t-shirt, apron, dress or maybe make a cardboard hat to showcase the 100
Avoid using glue if possible and make attachments easy to remove when the 100 day excitement is long gone. For example, sewing on pom poms instead of permanent glue will be way easier to undo
If you must write text on clothing you want to wear again, think about using washable markers
Aim to make your costume reusable or un-doable, but also consider the possibility of passing it on to another child who can use it the following year. I know part of the fun is in the making, but there are plenty of families that don’t have a lot of spare time to do this
Upcycle things for your project and try to use things that can be easily recycled, reused or repurposed. Or dare I say, the costume might even be able to be adapted for Halloween, book week, parties or just as an addition to your home dress up box. (Those t-shirts with 100 plastic eyes are actually pretty horrific from a sustainably point of view!)
Zero Waste and Ecofriendly Costume Ideas for your 100 Days of School
Dressing up as 100-year-olds
Use clothing and accessories you already have at home, such as oversized sweaters, hats, and scarves, to create a "grandparent" look, or perhaps raid the grandparents closet
Use eco-friendly makeup or face paints to create wrinkles, age spots, and grey hair without the need for masks or wigs. You could dust hair with flour or corn-starch for grey hair or even use coffee grounds for age spots
Wear recycled or thrifted clothing items to create a vintage or elderly look and later donate the items back to an op-shop
Use recycled cardboard or paper to create walking canes or walking sticks as props
100 Days Smarter
Wear a t-shirt or dress made from organic cotton or sustainable fibres, featuring your own 100 Days Smarter design
Use eco-friendly fabric paints and markers to create your design on a plain t-shirt, dress or apron
Repurpose old clothing by sewing or attaching numbers 1 to 100 to showcase counting skills
Make a necklace or bracelet using recycled materials with 100 beads or charms. Or how about a froot loops necklace like this one from Kid Friendly Things to do

Dress up as a gardener or farmer, attach 100 small flowers or leaves to your clothing (these could be real or made from fabric scraps)
Use Flowers and leaves to temporarily dye pale clothing, you can even use a hammer for this one to bash the colours out of the plant materials, its pretty fun! (it will more than likely also wash out pretty easily)

Upcycle an old jigsaw puzzle(s) and attach 100 pieces to an outfit
Superheroes and Capes

Use non-toxic face paint or cut out some old fabric to create a superhero mask
Dressing up as a specific theme with 100 items
Dress up as a 100-year-old athlete by wearing recycled sports clothing and attaching 100 fabric or paper medals or ribbons
Create a costume representing a 100-year-old scientist or inventor, using recycled materials to make lab coats and attaching 100 recycled test tubes (I'm wondering if coffee pods could somehow be used for this, if you have an idea let me know!)
Dress up as a 100-year-old book character, using recycled materials to create the character's outfit and attaching 100 paper cut-outs of the book's title, cover image, characters or pages

Make your own version of this incredible leaf dress (you can read more about it at Hippie In Disguise) the autumn leaves work well in Australia but if you're in the summer months this could totally work with green leaves
Dress up as a 100-year-old artist, wearing a smock made from upcycled fabric and attaching 100 small recycled paintbrushes or mixed art supplies
Of course these ideas are just suggestions (some are harder than others) and I’m sure many of you will be inspired with your own unique ideas, but it's super important to make sure whatever costume you choose to make and wear is both safe and comfortable and of course, make sure any materials used are safe, non-toxic, and age-appropriate for your kids.
