These celebrities clearly had Disney on their minds for Halloween ... 'cause they went ALL OUT dressing up as some of their favorite animated characters!!!
Allison Williams, Khloe Kardashian, and Kylie Jenner are only some of the big names that took serious inspo from the 'House of Mouse' ... and they all look pretty damn good doin' it!
Kris Jenner didn't hold back, dressing up as Jack Skellington from "The Nightmare Before Christmas" ... singer Chase Hudson -- AKA Huddy -- also put in the work to look like the 'Bone Daddy' himself.
Social media star Cameron Dallas and his boo Madisyn Menchaca fell down the rabbit hole one year ... donning some serious costume detail to portray Alice and The Mad Hatter from "Alice in Wonderland."
It might've all started with a mouse, but it clearly ain't ending there for these celebs!!!
