Before you can begin to build your costume or cosplay, you'll want to pinpoint just what the purpose and intent are behind your creation. Will it be a quick one-time project for a Halloween party or other fun event? Or an accurate period piece for an historical re-enactment? Or perhaps an original fantasy-style costume for a television or film production? Whatever your purpose behind your costume creation, there will be common construction techniques and materials you can use to build almost any type of costume/cosplay you might want, and those will be outlined further on in this chapter.
