animals or cartoon characters pajamas "disguise pajamas"

kigurumi employs full-body animal pajamas with hoods or hats styled after animals or cartoon characters. Called "disguise pajamas", the clothing is normally worn non-commercially as  street fashion. The wearers are referred to in as kigurumin. The clothing does not function as a performance costume. The pajama outfits tend to be made of thin material and conform to the body in the manner of normal clothing. The hoods or caps do not cover the face.

In English-speaking countries kigurumi are referred to as costumed characters, animal costumes, mascot costumes, adult onesies or fursuits depending on the context. Fursuits are mascot-style costumes that represent animals and cartoon characters according to established styles within the furry fandom. Such suits completely cover the performer's body and are often padded as necessary to render the appropriate shape.

Variations of fursuits exist informally called "partials" in which only a costume head and costume hands/arms are worn, with standard clothing covering the rest of the body. Partials typically, but not always, include standard shoes rather than fursuit feet-paw-shoes, due to the fact that the wearer is trying to look casual, and the costume feet would be an additional effort to create. Also, keeping furred feet soles from being ruined while walking is already a problem for people wearing standard fursuits, who sometimes create sandals to protect the soles.
