Have you binged Squid Game yet? It's the most popular show ever on Netflix - and the perfect inspiration for a Halloween costume! In this tutorial, I'll show you how to make a DIY Squid Game costume, based on the green numbered tracksuit that Squid Game players must wear in the Korean drama.


To make this Squid Game costume, the thrift store and dollar store will be your best friends. The character I chose is player 067, Sae-byoek, one of the bravest Squid Game players. A North Korean defector, she was in the games to help her mother and little brother.


If you’re planning a Squid Game Halloween costume this year, then follow along with this DIY tutorial. Or, take a look at my other tutorials on Squid Game DIY costumes for the other characters: How to Make a DIY Squid Game VIP Mask and How to Make a DIY Squid Game Guard Red Suit and Mask.

Tools and materials:

  • Tracksuit
  • Plain white t-shirt
  • Cardboard
  • Pen or marker
  • Fabric paint (acrylic works as well)
  • Paintbrush 
  • Number stencil (optional) - I used number stickers from the dollar store
  • White tea or dish towel (not terry but more of a lint-free cotton or linen type fabric)
  • 1- or 2-inch wide elastic
  • Glue gun and glue
  • Scissors


A bluish-greenish tracksuit would be ideal. If you can’t find a set, then use a pair of oversized sweatpants and a zip-up jacket with a collar in the blue/green color. You may find these in the men’s section or look for a size bigger than you would typically wear.

Drawing the player's numbers for the costume

1. Paint the t-shirt

I didn’t have number stencils, so I hand-drew the numbers. I used a dark marker on a piece of cardboard thick enough to see it through the t-shirt fabric.

Place the cardboard underneath the front of the t-shirt to trace the number in paint. The cardboard serves as a guide and helps prevent the paint from bleeding through to the other side.


Mix paints you have to get that bluish-greenish color featured in Squid Games. Mix up a lot of the paint because we need to paint a lot, and we don’t want to run out and have to mix it up when we’re halfway through. 

Painting numbers on the Squid Game tracksuit

Paint the numbers on the shirt and then paint the sleeves from the bottom of the sleeve upward. Use the shoulder seam as your guide.

Be mindful that acrylic paint on the sleeves will be a little crusty. While fabric paint would be ideal, this is a costume, not for constant wear.

2. Paint numbers for the Squid Game tracksuit

The Squid Game tracksuit jacket has two numbers: one in the front on the left side and the other on the back in the center. I couldn’t find a number stencil, but I did find number stickers at the dollar store. 


I put the stickers on a white dishtowel. I then painted a rectangle in the paint over the numbers.

Cutting out the player numbers

I made two of these. I let the paint dry. The reverse stencil gives a nice crisp line. If you find a number stencil and can use white paint on the jacket, that would be ideal, but this works almost as well.

3. Attach the player numbers to the jacket

I cut the rectangles out and then hot-glued them to the jacket. One goes on the left side on the front of the jacket.

The other goes in the back in the center.

4. Attach the white stripes

Another detail of the Squid Game tracksuit is the white stripes on the jacket and down the pants.


I used an elastic band from the dollar store. Hot glue the elastic at the top of the shoulder, following down the arm.

I then add elastic down the sides of the pants. Elastic works well because it has some give to it and isn’t stiff.

I added some clip-in bangs to amp the Squid Game player costume up as much as possible. I am thrilled at how this came out!

This DIY Squid Game costume is pretty close to what you see in the show for a fraction of what Squid Games costumes would cost to buy. I was able to match the paint color pretty well too!
