Here’s a Halloween idea as comfy as it is silly!
Kigurumi comes from a combination of two Japanese words: Kiru (“to wear”) and nuigurumi (“stuffed toy”) which is very appropriate since you’re literally dressing yourself as a stuffed animal or cartoon mascot. The equivalent of kigurumi in English is “splash mascot”. You see them pretty often from Mickey Mouse in Disneyland to the poor soul working as a sign spinner dressed as an anthropomorphic ice cream cone.
In Japan, there is another subset of kigurumi in the form of giant stylized onesies called “disguise pajamas” that became a big fashion item among the girls of Harajuku literally overnight in the early 2000s. What’s better than raiding the giant Don Quijote stores (think of them as 24hr Japanese Walmarts) and buying funny animal pajamas to wear after night of heavy partying?
