Professional costume designers generally fall into three types: freelance, residential, and academic. •
Freelance designers are hired for a specific production by a film, theatre, dance or opera company. A freelancer is traditionally paid in three instalments: Upon hire, on delivery of final renderings, and opening night of the production. Freelancers are not obligated to any exclusivity in what projects they work on, and may design for several productions hired by a specific theatre, dance or opera company for an extended series of productions. This can be as short as a summer stock contract, or may be for many years. • A residential designer is consistently "on location" at the theatre—at hand to work with costume studio and other collaborators. A residential designer's contract may limit the amounts of freelance work they are allowed to accept. Residential designers tend to be more established than strict freelancers, but this is not always the case. • An academic designer is one who holds professorship at a school. The designer is primarily an instructor, but may also act as a residential designer to varying degrees. They are often free to freelance, as their schedule allows. In the past, professors of costume design were mostly experienced professionals that may or may not have had formal post-graduate education, but it has now become increasingly common to require a professor to have at least a
Master of Fine Arts in order to teach. Both residential and academic designers are generally also required to act as Shop Master or Mistress of an onsite costume shop, in addition to designing productions. In a resident theatre, there is almost always a shop staff of stitchers, drapers, cutters and craft artisans. In an academic environment the shop "staff" is generally students, who are learning about costume design and construction. Most universities require costume design students to work a specified number of hours in the shop as part of their course work. ==Unions in the United States and Canada==
