DIY Cookie Monster Costume

Three cheers for DIY Halloween costumes

You guys, I feel like the existence of Sexy Mister Rogers is probably enough to convince you to turn your back on the Costume Industrial Complex and spend an hour making your own costume, right?

Or maybe that’s just me and my sister, who have a loooong history of making our own costumes and also of people telling us our dad reminded them of Mister Rogers.

But if you need a little more convincing, may I present DIY, no-sew, totally adorable Cookie Monster?

DIY Cookie Monster Costume

We made this costume for Adelaide several years ago. I wish I could find the blog post that originally taught me how to do it, but it seems to have vanished from the internet. So here’s our version, which went over like a charm circa 2015 and is slated to be worn again this year by Celia.

Full instructions, including a low-key printable template for your felt cutouts, are right here below. We used black leggings (which you can rewear) and a white tank (which you could rewear, but it would still have cookies on it) because that’s what we had, and we thought it looked cute. You could totally also go all royal blue if you’re into that kind of thing.

If you like, you can shop straight from your phone or computer and buy just about everything you’ll need on Amazon through the links below. You’ll end up with a bit more than you need if you do that, but it couldn’t be easier. Or head to your local fabric store and craft store to get the goods.

This easy, no-sew DIY take on a Cookie Monster costume makes a cute (and dare I say kinda stylish?) Halloween costume for a slightly older kid or even an adult. The estimated cost is based on stopping by a craft store and picking up just the amounts you'll need for the project. If you'd rather buy on Amazon, I've got recommended products below to make it easy, but you'll be buying more of some items than you need for one costume.

Serves 1 costume


  • Royal blue tulle (see note about quantities)
  • Light blue tulle
  • 1-inch-wide elastic for sewing
  • Felt (black, white, tan/light brown)
  • 1 Royal blue feather boa
  • 1 Plain black or brown headband
  • Black leggings (can be reworn)
  • 1 White t-shirt or tank top (or use royal blue if you like)


  • Printable felt cutouts pattern (linked in instructions)
  • Hot glue gun
  • 1 piece of cardboard that can fit inside the t-shirt


  1. Cut a piece of elastic to fit around the waist as snugly as you like, and tie the ends together securely.
  2. Decide how long you would like the skirt to be, and cut two-inch-wide strips of tulle twice that length plus about an inch more.
  3. To assemble the skirt, fold each piece of tulle in half. Place the folded end behind the elastic. Bring the loose ends, together, up over the elastic and thread them through the loop made by the folded end. Pull to secure. Keep going, interspersing royal blue and light blue strips as you like, until the skirt is nice and full.
  4. Using the printable pattern, cut out as many tan felt circles as you like for cookies. Cut out two white circles for the eyes. Cut out lots of small black rough circles for chocolate chips and two black circles for the eyeballs. Cut out two white circles for the eyes, one black mouth, and one tan half-eaten cookie.
  5. Using the hot glue gun, glue the chocolate chips to the cookies, the eyeballs to the eyes, and the half-eaten cookie to the mouth. Then glue the cookies to the shirt (place the piece of cardboard between the front and the back of the shirt so they don't stick together) and the face to the skirt.
  6. To make the headpiece, cut off a small piece from one end of the boa and glue it to the headband. Once dry, your costume is ready to wear!


The yardage of tulle you will need depends on both the height of the costume wearer and, of course, the width of the tulle you are buying. If you order through the Amazon links below (which is sold on 6-inch-wide spools), buy one spool of each color, and you'll have some left over. You will cut the tulle lengthwise into 3 strips of 2 inches each, as long as you need them. (See instructions.) If you're buying at a fabric store, the bolts are likely to be 54" wide, which should be long enough to cut the strips crosswise unless the wearer is very tall or wants a very long skirt. In that case, you can buy three yards of royal blue and two yards of light blue.
