Coolest Adult Cookie Monster Costume

I always love putting together costumes for Halloween. After struggling to figure out how to make this year’s costume, I was walking through the fabric store, saw some blue fur and instantly had a new idea. COOKIE MONSTER! I pulled out my phone and looked up some pictures to get an idea of what would be needed.

After taking a few quick measurements in the store, I decided that 4 yards of fabric would be about right. The cost of the fabric was $91 and was the main cost of the costume. The total cost was a little less than $120. I originally thought of making a top and bottom half to the costume but realized it would look much better if it was seamless. I went to the thrift store and found a set of work coveralls. The only in-progress picture shows the coveralls from the front. I cut open the back in order to get in and out of the costume.

I used hot glue to attach some fabric around the arms and belly and then stuffed the fabric. This added some bulk to the Cookie Monster. It was also very helpful to stuff the coveralls with towels in order to have it keep it’s shape. I then started the process of attaching the fur. This was mainly done with hot glue. Since the fur is pretty thick, as long as you get the seams really close, you didn’t see them. I laid out the stuffed coveralls over the fabric and cut out the basic shape and then did my best to wrap, cut and glue everything into place.

The hands were an old pair of heavy duty work gloves that I glued the fabric to. The feet were made of an old pair of sneakers with a piece of cardboard duct taped to the bottom to make them bigger. I started attaching the blue fur fabric, added a little stuffing to make the shape right, and then finished covering them. At that point, it was just the head and neck to go. I made the mouth out of cardboard and used a couple wire pieces to help hold its shape. I then took an old baseball cap, cut the brim off and hot glued a cardboard ring to the top. After that, I figured out the basic length and width of the head and cut out another cardboard piece and glued it to the cardboard ring.

I glued the mouth to the front part of the cardboard and then used some foam pieces (camping pad and carpet padding) to build up the shape of his head. I then used a little stuffing to round off the edges and covered it in fur. Overall, the neck was the hardest part. At that point, I did have to do some sewing (just a needle and thread) to add some additional fabric and get it looking right.

I also made the costume for my wife. It was just cardboard, fabric and stuffing and cost about $15. The only real issue with the costume was that it could be fairly warm. I went to a couple costume parties in town and I found out one thing really fast. People LOVE the COOKIE MONSTER. I took hundreds of pictures with people which was pretty fun. Wow…. I almost forgot. The eyes are Styrofoam balls that have hard plastic tubes inserted through them. I attached black plastic pieces (pupils) to fairly rigid wire and stuck the wires through the tubes and bent the wire in back to hold them in place. This allowed the pupils to move back and forth to give him the googly eyes.

I’m already looking forward to figuring out what next year’s costume is going to be!

      I have almost completed my own cookie costume and thought I’d look on the net to see if anyone had done something similar.
      How did the hot glue hold up after a night of wearing it? I took the long route and cut and sewed the entire costume. Made the suit and the gloves by hand and stuffed it with cotton from a craft store. I used a hard hat for the head and see out the mouth. Also made a chin strap and rigge the mouth to open and shut when I speak.
      I love that there is someone else out there that is a crazy as I am to go through such a process to make such a great suit. Kudos dude. It looks great!
      Again, did the suit hold up?

      Hi there! Super great costume! Where did you end up getting your cookie monster fur from? I would love to make a costume for my son’s bday party! Thanks!

      Have not looked on here for a while. The fur came from a local fabric store. I was actually looking for material for another costume. When I saw the blue fur, I completely changed my mind on what I was going to be, did some quick math to figure out how much I would need, and bought it. As far as the hot glue, it held up great. I’ve used it in many costumes and have never had any come apart. IF I can hot glue it instead of sew it, I will since it holds up really well. My wife’s costume was just two large cardboard circles. I cut out the fabric in a larger circle, enough to be able to hot glue it to the back side of the cardboard around the edge and then stuff it. I then cut out a circle of fabric the same size as the cardboard circle and glued that to the back side of the cardboard. I used dark brown felt fabric to make the chips and stuffed them. Once the chips were made, I glued them to the cookie. Did the same to make the second cookie, and then connected the two with straps so it could hang on her shoulders.
      One of my favorites that I made, but it is quite hot to wear.

    • Talia

      im using two pieces for the body. i couldnt find coveralls. So i am kind of lost with the head piece. I have the shirt and shorts, oh and gloves covered but i cant figure out the head…

    • Talia

      is the neck connected to costume or a different piece tucked in?

    • Brian Zehner

      It is connected to the costume everywhere except the back side but I imagine you could do it separate also. THis allows you to pull the head off and let it hang down if you want to take a break from having it on. The head is just cardboard and foam formed into the right shape and hot glued on a baseball cap.
