Party Princess is a term associated with a person who entertains children at birthday parties, often dressed as different Disney characters. The most common party princesses costumes are Elsa, Cinderella, Sleeping Beauty and The Little Mermaid. Party princesses generally perform at private birthday parties for young girls - they sing, dance and play with the girls, all-while maintaining a party theme based on the character they're dressed up as. Party princesses are most common in upper-middle-class and upper class areas and are a common sight in Beverly Hills and North Hollywood.
