DIY Monsters University Family Costumes

I’m so excited for this costume post today! I am finally sharing some details about how to make our upcycled/DIY family Monsters University costume theme last year! And, be sure to keep scrolling through as there is a MEGA list of DIY Halloween costumes to follow! 🙂 SO much DIY costume fun! DIY Monsters University Family CostumesWe LOVE doing family-themed Halloween costumes (we’ve already done pirates (twice), Star Wars, Nemo/Snorkeling, and a bug theme). It’s hard picking favorites, but our Monsters University theme last year was SO much fun! Living in Phoenix, these costumes would have been almost impossible (way too hot). But, we spent Halloween in Nebraska last year. And, the cooler weather was PERFECT for an entire group Monsters theme. And, really, doing the costumes was NOT tough at all – especially with the help of my super crafty mom! 😉

Now, right off the bat I need to say that we did NOT make the Mike & Sulley costumes (but we did embellish). The cost of the fur/fleece alone needed was almost the same price as the costume we bought and we decided that those two were just too labor intensive. So, we bought those costumes and then went from there. For both the boys, we made “MU” trick or treat bags (<— click for the bag directions tutorial).

If you look closely at the picture, you can see that the Sulley costume was actually too small. So, we found fleece that matched almost exactly & used that to lengthen the costume and then made some large Sulley-feet shoe covers. For Sulley’s hands, I found blue knit gloves. For all the claws on both the hands and feet, we cut black stiffened felt & cut in the shapes we wanted. For the hands, I just hot-glued on the claws by pinching them into the tips of the gloves. For the feet, we stitched the claws on. DIY Mike Wazowski Monster Costume Hands & feetMike Wazowski:

We also embellished Little Brother’s Mike costume by adding hands and feet. I couldn’t find green gloves. So we just went with cream and hot glued on some green felt (as close a match as I could find). Again, we used stiffened felt (just in gray this time) for Mike’s claws. The feet (as you can see) were considerably harder. We found that bright green fleece (which was great since the edges don’t fray). But, to get the long look of Mike’s toes, my mom sewed small tube casings that we stuffed. Then, we stitched those long toes on to the shoe covers that we made. DIY Family Monsters CostumesRandom Monsters U monsters:
For the rest of our Monsters U group, we just had a bunch of random fun! This is where you can let your creativity shine–really, you can do whatever you want here. If you’ve seen the movie, there are SOoooo many different kinds of monsters – all kinds of colors, spots, spikes, scaly, slimy, hairy, horns, claws, polka dots, big, small – you name it and it works. So, I decided to go the upcycle route here and hit up some local thrift stores for inspiration. The base for our adult costumes were some cheap matching sweat suits (less than $10 each). I didn’t care what color, I just was going for matching tops and bottoms. We had a Monsters University hat from a fun Disney event. So, that worked for Mr. Mom Endeavors. And, the sweatshirt I found had a hood – which was PERFECT for creating an awesome monster look!

Really, look for anything that could create a fun look. I bought a bright orange feather boa, a crazy furry scarf, a cheap green fuzzy blanket, a fuzzy black that already had horns, and part of a dragon costume (that was missing pieces). My costume also used some felt pieces (for the polka dots). And, just like with the Mike & Sulley, we used some cheap $1 knit gloves & added claws.Making Monsters CostumesOn the hood of my costume, we sewed in the horns (that we cut off the cheap hat I found. Then, I hot glued on a felt eyeball (just created with different sized felt circles) and hot glued on cut pieces of the feather boa around the horns. AWESOME! My outfit was a zip-up hoodie & I didn’t want the zipper to show. So, we created a simple Monsters University T-Shirt (using the same method as with the trick or treat bags). SUPER easy! DIY Monsters University T-ShirtI decided to coordinate Mr. Mom Endeavors’ and Baby Brother’s costumes, a bit. For Baby Brother, I used the pieces off the dragon costume I found and embellished. I cut the same fuzzy green blanket to add texture and fun to both costumes.  On Mr. Mom Endeavors’, there were spots all over and on Baby Brother, I added it to the belly. Those were just hand-sewn on (basically just barely tacked) and then we put some hot glue on for extra hold. We also cut up pieces of a fuzzy scarf to add to the neck & feet for some added texture & color. We also added an eye ball to Baby Brother’s costume (again, just cut felt) and added some pieces off a black feather boa. They looked SO cute together!!! Upcycled Monsters CostumesAgain, the beauty of this theme is that for the extra monsters you can do anything you want! Just get a variety of colors & textures and go to town. Adding a few recognizable logos (like on the bags and the shirt) then really helps tie the whole thing together! We had SO much fun with this theme…and can’t wait for another Disney character family costume theme again this year so stay tuned for that! DIY Family Monsters Halloween Costume
