A folk costume (also regional costume, national costume, or traditional garment) expresses an identity through costume, which is usually associated with a geographic area or a period of time in history.
 It can also indicate social, marital or religious status.
 If the costume is used to represent the culture or identity of a specific ethnic group, it is usually known as ethnic costume (also ethnic dress, ethnic wear, ethnic clothing, traditional ethnic wear or traditional ethnic garment).
 Such costumes often come in two forms: one for everyday occasions, the other for traditional festivals and formal wear.
The Carnival of Satriano (Italian: "Carnevale di Satriano" ), held in Satriano di Lucania, Italy every February, is one of the country's many carnivals.

 The event is among the most important carnival traditions of the region and of Italy and it is unique in that participants wear costumes, or masks, of bears, hermits, or lent.
A Renaissance fair, Renaissance faire, or Renaissance festival is an outdoor weekend gathering, usually held in the United States, open to the public and typically commercial in nature, which purportedly recreates a historical setting for the amusement of its guests.
 Some are permanent theme parks, while others are short-term events in a fairground, winery, or other large public or private spaces.
 Renaissance fairs generally include an abundance of costumed entertainers or fair-goers, musical and theatrical acts, art and handicrafts for sale, and festival food.
 Some offer campgrounds for those who wish to stay more than one day.
 Many Renaissance fairs are set during the reign of Queen Elizabeth I of England.
 Some are set earlier, during the reign of Henry VIII, or in other countries, such as France, and some are set outside the era of the Renaissance; these may include earlier Medieval periods (including Vikings), or later periods, such as 17th-18th Century pirates.
 Some engage in deliberate "time travel" by encouraging participants to wear costumes representing several eras in a broad time period.
 Renaissance fairs encourage visitors to enter into the spirit of things with costumes and audience participation.
 Many welcome fantasy elements such as wizards and elves.
A cavalcade is a procession or parade on horseback, or a mass trail ride by a company of riders.

 A cavalcade may also be a pilgrimage.

Cosplay (コスプレ , kosupure ) , a contraction of the words costume play, is a hobby in which participants called cosplayers wear costumes and fashion accessories to represent a specific character.

 Any entity that lends itself to dramatic interpretation may be taken up as a subject and it is not unusual to see genders switched.
 Favorite sources include anime, cartoons, comic books, live-action films, television series and video games.
