The first pattern, “Doors,” has a variety of colorful doors, in the style of the movie’s end credits. The pattern also features Mike, Sulley, Boo, and others peeking through the doors. Dedicated Pixar fans will even find a reference to the classic “A113” easter egg. The second pattern is called “The Scare Floor” and features a colorful mashup of characters from Monstropolis, including Mike, Sulley, Boo, Roz, and Randall.

Both shirts are made from RSVLTS’ signature Kunuflex material, which gives them some stretch. The adult shirts will cost $65, while the toddler sizes cost $39. They will be available to shop exclusively from the RSVLTS site, where Disney fans can also find button-down shirts with patterns inspired by Disney Villains, Toy Story, Soul, and Coco.
