The wearing of costumes has become an important part of such holidays and festivals as Mardi Gras and Halloween, and (to a lesser extent) people may also wear costumes in conjunction with other holidays, such as Christmas and Easter. Mardi Gras costumes usually take the form of jesters and other fantasy characters, while Halloween costumes traditionally take the form of supernatural creatures such as ghosts, vampires, pop culture icons and angels. Christmas and Easter costumes typically portray mythical characters such as Santa Claus (by donning a santa suit and beard) or the Easter Bunny by putting on an animal costume. Costumes may serve to portray various other characters during secular holidays, such as an Uncle Sam costume worn on the Independence day for example.
In Judaism, a common practice is to dress up on Purim. The Jews celebrate the change of their destiny. They were delivered from being the victims of an evil decree against them and were instead allowed by the King to destroy their enemies. A quote from the Book of Esther, which says: “On the contrary” is the reason that wearing a costume has become so popular among the Jews on this holiday.
Costumes also serve as an avenue for children to explore and roleplay. Children can dress up in various forms; for example characters from history or fiction like pirates, princesses or cowboys, common jobs like nurses or police officers, or animals such as those seen in zoos or farms.
