Updated on July 22, 2014

Mike and Sulley


Choosing a great Monsters University costume for this Halloween

Do you or your kid want to dress like a monster this Halloween? Monsters University costumes are some of the most fun and colorful options that are going to be popular this year.

Being in the theme of scariness and monsters, these costumes are ideal for Halloween. As always, all of Pixar's movies have resulted in great demand for their characters' costumes. This prequel to Monsters Inc. was released in 2013 but the characters won't be out of fashion anytime soon! Although the main characters are the same as those in the original, they have been updated to reflect their younger looks.

The charming and wise story of how Mike and Sulley came to be friends before their adventures in the original movie has resonated with children and adults. It teaches that sometimes, no matter how hard you wish for something or how hard you work at it, you won't always succeed at it, but you can try a different approach or new idea and succeed. It also teaches that two completely different people can become friends and endure.

Here are some great full suit and head piece options for monsters university costumes for kids and adults.

You'll need a baseball varsity Letterman style jacket in blue with white sleeves and blue and white ribbing for the collar, cuffs and hem.

Using blue, white and black felt, cut out the required shapes and stick them together with glue before attaching the whole logo to the front pocket spot on the jacket.

Monsters University hoodie hats

If you want to look the part but don't want to dress up from head to toe in monster regalia, why not get a hoodie hat of your chosen character and color coordinate the rest of your outfit?

A Monsters University costume be put together with Mike's or Sulley's character hoodie and paired with a blue t-shirt for Sulley or a green t-shirt for Mike.

A cool thing about these hats is that if you're in the mood for it, they can be used for winter outdoor activities. You could also remove the horns if you prefer!

The Story of Monsters University

In Monster's University, Mike Wazowski is determined to to learn to become a scarer, an important career, as children's screams are what keep monsters alive. However, he isn't the typical scary creature and even though he has the brains. Sulley, on the other hand, is a natural scarer and intends to breeze through university on the strength of his family's reputation.

Their ensuing rivalry and relationships with other monsters on campus amuses both kids and adults alike, and the story ends with Mike and Sulley eventually becoming friends before they take up their jobs at Monsters Inc.
