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.
 Held on the Friday, Saturday and Sunday before Fat Tuesday (a "Mardi Gras" festival), it has been conducted for centuries.
 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.
 The focus of a cavalcade is participation rather than display.
 Often, the participants do not wear costumes or ride in formation.
 Often, a cavalcade re-enacts an important historical event and follows a long distance trail.
 A cavalcade may also be a pilgrimage.
Video game collecting is the hobby of collecting and preserving video games, video game consoles, and related memorabilia.
 Most video game consoles, and their games, are considered to be collectors' items years after their discontinuation due to their functional longevity and cultural significance.
 Collectors usually narrow their search to games holding characteristics they enjoy, such as being published for a specific video game console, being of certain genre, or featuring a specific character.
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.
 Cosplayers often interact to create a subculture, and a broader use of the term "cosplay" applies to any costumed role-playing in venues apart from the stage.
 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.
Putong or tubong is a ceremony occasionally performed in the Province of Marinduque, Philippines, in which visitors are honored and welcomed.
 The ceremony takes the form of the eponymous song which is a call for "thanksgiving, hope and prayer for a long, blessed life".
 The ceremony begins with the celebrants gathering around the home of the host, they begin singing slowly as they enter the house, accompanied by a guitarist.
 They women wear costumes such as a kimono or a saya, while the men wear a barong, and they carry baskets of flowers, palm leaves, or coins.
 Once in the home, the tempo of the song picks up until it reaches a crescendo as a crown is placed on the honoree's head.
 After being crowned, the honoree is then showered with the contents of the celebrant's baskets.
 The celebration ends with all the participants shouting "Mabuhay", which means "long life".
The following is a list of a notable people who have at one time been known to cosplay (コスプレ , kosupure ) .
 Short for "costume play", it is an activity in which participants wear costumes and accessories to represent a specific character or idea from a work of fiction.
Nuo opera or Nuo drama () is one of the most popular folk operas in southern China.
 Characterized by its special features such as ferocious masks, unique dresses and adornments, the strange language used in performance, and mysterious scenes, Nuo opera has been selected as one of the non-material cultural legacies of China.
 The opera is a religious performance intrinsic to the culture of Nuoism, a type of Chinese folk religion.
 The purpose of Nuo opera is to drive away devils, disease and evil influences, and also to petition for blessings from the gods.
 Singing and dancing are included in Nuo opera and performers wear costumes and masks.
