It’s almost that time of year again…HALLOWEEN!!! I absolutely love Halloween, and for the past few years my kids have chosen to dress up in coordinating costumes, and last year was no different.
Somewhere around the summertime, my daughter became OBSESSED with Monsters Inc and I realized how much she resembled Boo from Monsters Inc.
LIGHT BULB as Gru from Despicable Me says.

Make the Boo DIY Costume
Here is how extremely easy this is, the only thing you need to do is get them dressed! That’s it! I liked this Boo Monsters Inc costume version rather than the boo from monsters inc that is made from the chair fabric.
My daughter was so comfortable and it was very in expensive. I think the whole costume cost less than $20. She still wears this outfit to sleep in all the time.
Take Pictures of Boo Costume Monsters Inc at all the Events

My daughter had several events to wear this Boo Monsters Inc costume. The kids school always does a Halloween Program where kids are encouraged to wear their costumes while they sing songs. Unfortunately, she cried the whole time.
Bless her heart!
We go to my in laws Lake House every year for something called “Boo on the Lake.” (Aptly named for that year) They drive their boat around the lake and the kids trick of treat at the different docks. It’s so fun!
About a week before Halloween is my daughter’s birthday and last year the theme was “Boo, I’m Two!” which she wore the boo diy costume and was given her boo doll. Aren’t they so cute!
Lastly, of course, she wore it for Halloween. Easiest costume I’ve ever “made.”
Sully and Boo Costumes


Here are some pictures of my kids together. My son decided to match his sister so they could have matching Sully and Boo Costumes. This is another easy and affordable costume idea that is comfortable and easy!
I ordered this Sully costume from Amazon. He still wears it to play dress up and wear around the house. It also kept him super warm on the cool Halloween evening for trick or treating.
Final Thoughts
The Boo DIY costume is pretty simple and inexpensive costume for any age! I think it is very sustainable because the clothing items can be worn again and again instead of only once for a couple hours.
You may even have these items on hand and spend ZERO DOLLARS!
How Awesome is that?!? Sully is a cute addition if you have another child that wants to join in the Monsters Inc Halloween Costumes fun! Grab a Little Mikey from ebay or a stuff Sully or Mike Wazowski for an added touch!
