Adult baby is where an older person dresses up in baby-like clothes and wears a diaper. Sometimes the wearer just wishes to look like a baby again, most likely for the cuteness and innocence that is inherent in babies. Other times it is used as a type of roleplay. In addition, it can have connections in Domination and Submission play. It can have sexual and nonsexual appeal, depending on the person looking at it and the way in which it is portrayed.
