Are you looking for some adorable Monsters Inc Costumes for the whole family? I have a few easy ideas for everyone’s favorite monsters Mike Wazowski and Sully costumes.
Ok so maybe your favorite monsters isn’t Mike, maybe it’s Sulley or Boo. Just please don’t tell me it’s Randall. He is the worse and definitely is no big hero. 😉 Either way Monsters Inc is an excellent group costume theme for Halloween parties or Disneybounding in the parks.
And remember it’s not all scary, the Disney+ show Monsters at Work shows how new monsters learn to be come jokesters (vs. Scarers) at Monsters Incorporated with the help of old friends like Mike, Sulley and Roz.
This fun show, along with the classic movies ensure that Monsters Inc Family costumes would be a big hit at your next Halloween party.
Mike and Sully Costume DIY
Monsters Inc and Monsters University were favorites of my boys when they were little. And they loved the easy Sully and Mike Wazowski costumes I made. Both are simple costumes that can easily be scaled up for adult costumes. You know I love to DIY Halloween costumes, especially Disney costumes!
I was inspired by the bright and appropriately colored shirts I found in my craft supply stash. Snagging cheap t-shirts at your local discount store and adding a few details i all you need for these adorable Mike and Sulley costume ideas.

Mike Wazowski Costume Materials
Monsters Inc Costume Tutorial
Starting with the t-shirt, I created one huge Mike Wazowski eye using white, green and black felt. I attempted to use some fabric glue but had better luck with my hot glue gun!
Try to off center the eye slightly, if everything is perfectly centered, the eye looks a little odd. Keeping it simple, I skipped his teeth and made a simple smile using black felt.
DIY Monsters Inc Hat
Mike’s hat is my favorite part of the Monsters University costumes, it was so easy and turned out awesome. I started with a plain blue baseball cap I found at the Dollar Tree. I printed a Monster University logo I found online (using a quick google search) and used it as a template.
I used light blue, white and black felt to create the logo for the hat. I don’t trace my templates onto the felt. I like to use double-sided tape to attach the template to the felt and then cut around it. Then I don’t have to worry about pencil marks and it’s easy to peel the template off of the felt.
Glue the MU logo together and then glue it on the front of the cap. I have seen this hat being sold at Disney World, well the MU part at least, you’d still have to add your own horns to the side.
Mike and Sully Costume Hat
The best part of the hat is the horns. Quinn inspired me to put the horns on the hat. He knew Sulley was getting horns and reminded me that Mike also has monster horns. I realized I could make a small pair of horns with leftover white felt – similar to Sulley’s. Then I stitched them to the side of the hat.
Easy Sulley DIY Costume
Sulley Monsters Inc Costume Materials
- Blue t-shirt (great for toddler sizes and bigger)
- knit cap (I wanted blue but used purple)
- Blue, purple, and white felt
- Stuffing material
I think a blue hoodie would make a great Sulley costume base but I already had the blue t-shirt. My plan was to find a matching blue knit hat.
Unfortunately, I had no luck but did run across a purple hat that matched Sulley’s spots, so I ran with it. The costume isn’t perfect but it’s cute and the colors coordinated well.
Sulley Costume Hat DIY
I cut spots out of purple felt and glued them on to Sulley’s shirt. I played with the placement a little bit before attaching them, I wanted different sizes placed randomly on his “fur”.
Again a blue hoodie would be ideal for Sulley, I settled on a knit hat to keep the costume super frugal. Plus you could size the hat up for a big head if making an adult costume.
I found this purple knit hat at the dollar store and it worked fine. I had a 2nd blue shirt and used that material to make the spots for the hat. It helped coordinate the colors perfectly.
The horns themselves were easy to make using white felt. I played around a little with horn template size to get the right size horns for the cap.
Then I cut the horns out of white felt, sewed them together and added a tiny bit of stuffing. A sewing machine would make this a bit easier but I did fine without.
Originally I thought about attaching them to a headband but I couldn’t imagine Elliot wearing a headband without complaining. Alternatively, you could just find a pair of costume devil horns and spray paint them white to wear.
Happy Halloween from my Top Scarers!
