Halloween costumes are costumes worn on or around Halloween, a festival which falls on October 31. An early reference to wearing costumes at Halloween comes from Scotland in 1585, but they may pre-date this. There are many references to the custom during the 18th and 19th centuries in the Celtic countries of Scotland, Ireland, Mann and Wales. It has been suggested that the custom comes from the Celtic festivals of Samhain and Calan Gaeaf, or from the practise of "souling" during the Christian observance of Allhallowtide. Wearing costumes and mumming has long been associated with festivals at other times of the year, such as on Christmas. Halloween costumes are traditionally based on frightening supernatural or folkloric beings. However, by the 1930s costumes based on characters in mass media such as film, literature, and radio were popular. Halloween costumes have tended to be worn mainly by young people, but since the mid-20th century they have been increasingly worn by adults also.
The custom of guising at Halloween in North America is first recorded in 1911, where a newspaper in Kingston, Ontario reported children going "guising" around the neighborhood. In 19th century America, Halloween was often celebrated with costume parades and "licentious revelries". However, efforts were made to "domesticate" the festival to conform with Victorian era morality. Halloween was made into a private rather than public holiday, celebrations involving liquor and sensuality de-emphasized, and only children were expected to celebrate the festival. Early Halloween costumes emphasized the gothic nature of Halloween, and were aimed primarily at children. Costumes were also made at home, or using items (such as make-up) which could be purchased and utilized to create a costume. But in the 1930s, A.S. Fishbach, Ben Cooper, Inc., and other firms began mass-producing Halloween costumes for sale in stores as trick-or-treating became popular in North America. Halloween costumes are often designed to imitate supernatural and scary beings. Costumes are traditionally those of monsters such as vampires, werewolves, zombies, ghosts, skeletons, witches, goblins, trolls, devils, etc. or in more recent years such science fiction-inspired characters as aliens and superheroes. There are also costumes of pop culture figures like presidents, athletes, celebrities, or characters in film, television, literature, etc. Another popular trend is for women (and in some cases, men) to use Halloween as an excuse to wear sexy or revealing costumes, showing off more skin than would be socially acceptable otherwise. Young girls also often dress as entirely non-scary characters at Halloween, including princesses, fairies, angels, cute animals and flowers.
Halloween costumes in the contemporary Western
Halloween costumes in the contemporary Western world sometimes depict people and things from present times and are sometimes read in terms of their political and cultural significance. Halloween costumes are sometimes denounced for cultural appropriation when they uncritically use stereotypical representations of other groups of people. Immigration and Customs Enforcement Secretary Julie Myers was involved in a scandal when she awarded "Best Costume" at the ICE Halloween party to an 'escaped Jamaican prisoner' dressed in dreadlocks and blackface.
