Halloween Girls Kissing

• Costumes
Halloween costumes are traditionally modeled after supernatural figures such as monsters, ghosts, skeletons, witches, and devils. Over time, the costume selection extended to include popular characters from fiction, celebrities, and generic archetypes such as ninjas and princesses.
Dressing up in costumes and going "guising" was prevalent in Scotland at Halloween by the late 19th century. Costuming became popular for Halloween parties in the US in the early 20th century, as often for adults as for children. The first mass-produced Halloween costumes appeared in stores in the 1930s when trick-or-treating was becoming popular in the United States.
Halloween costume parties generally fall on, or around, 31 October, often falling on the Friday or Saturday prior to Halloween.
