A party hat is any of a number of celebratory hats, most typically in the form of a conical hat made with a piece of thin paperboard, usually with designs printed on the outside and a long string of elastic acting like a chinstrap, going from one side of the cone's bottom to another to secure the cone to the person's head. Party hats are worn most often at birthday parties, especially by the guest of honor or at New Year's Eve celebrations] In the United Kingdom the hat is made of paper and is in the shape of a crown, and is most typically worn during a Christmas dinner. The party hat has its origins in the dunce cap worn by misbehaving or poorly performing schoolchildren from the mid-19th century to the early 20th century, with its festive decoration and society's positive attitude toward the wearer indicating a relaxation, or even reversal, of certain social norms.
