Here was supposed to be this lorem impsum thing, but I can't look at it anymore. So have a definition of cosplay instead. Prepare for a wall of text.
Cosplay, short for "costume play", is a performance art in which participants wear costumes and fashion accessories to represent a specific character or idea that is usually identified with a unique name. Cosplayers often interact to create a subculture centered on role play. A broader use of the term cosplay applies to any costumed role play in venues apart from the stage, regardless of the cultural context.
Favorite sources include manga, anime, comic books, video games, and films. Any entity from the real or virtual world that lends itself to dramatic interpretation may be taken up as a subject. Inanimate objects are given anthropomorphic forms and it is not unusual to see genders switched, with women playing male roles and vice versa.
The Internet has enabled many cosplayers to create social networks and websites centered on cosplay activities, while forums allow cosplayers to share stories, photographs, news, and general information. The rapid growth in the number of people cosplaying as a hobby since 1990 has made the phenomenon a significant aspect of popular culture. This is particularly the case in Asia, where cosplay influences Japanese street fashion.
Cosplay costumes vary greatly and can range from simple themed clothing to highly detailed costumes. Cosplay is generally considered different from Halloween and Mardi Gras costume wear, as the intention is to replicate a specific character, rather than to reflect the culture and symbolism of a holiday event. As such, when in costume, some cosplayers will often seek to adopt the affect, mannerisms and body language of the characters they portray (with "out of character" breaks). The characters chosen to be cosplayed may be sourced from any movie, TV series, book, comic book, video game or music band, anime and manga characters. Some cosplayers will even choose to cosplay an original character of their own design or a fusion of different genres (e.g. a steampunk version of a character).
Cosplayers obtain their apparel through many different methods. Manufacturers produce and sell packaged outfits for use in cosplay, in a variety of qualities. These costumes are often sold online, but also can be purchased from dealers at conventions. Japanese manufacturers of cosplay costumes reported a profit of 35 billion yen in 2008.[3] There are also a number of individuals who work on commission, creating custom costumes, props or wigs designed and fitted to the individual; some social networking sites for cosplay have classified ad sections where such services are advertised. Other cosplayers, who prefer to create their own costumes, still provide a market for individual elements, accessories, and various raw materials, such as unstyled wigs or extensions, hair dye, cloth and sewing notions, liquid latex, body paint, shoes, costume jewelry and prop weapons.
Most cosplayers create their own outfits, referencing images of the characters in the process. In the creation of the outfits, much time is given to detail and qualities, thus the skill of a cosplayer may be measured by how difficult the details of the outfit are and how well they have been replicated. Because of the difficulty of replicating some details and materials, cosplayers often educate themselves in crafting specialties such as textiles, sculpture, face paint, fiberglass, fashion design, woodworking, and other uses of materials in the effort to render the look and texture of a costume accurately.[4] Cosplayers often wear wigs in conjunction with their outfit in order to further improve the resemblance to the character. This is especially necessary for anime and manga or video game characters who often have unnaturally coloured and uniquely styled hair. Simpler outfits may be compensated for their lack of complexity by paying attention to material choice and overall high quality.
