Model agencies represent people who work as models in fashion, advertising, publishing, film and other media. They may recruit and assess new models, help develop portfolios and advise on suitable types of work, such as runway shows, catalogue photography, editorial shoots, product campaigns or promotional assignments. Some agencies specialise in particular areas, including child modelling, plus-size modelling, parts modelling or mature models. Agencies typically introduce models to clients, arrange auditions and castings, negotiate bookings and fees, and coordinate practical details such as schedules, usage rights and contract terms. They may also liaise with photographers, casting professionals, production teams and brands. The services and payment arrangements vary, so models and clients should check the agency's terms, including any commission, expenses, exclusivity and cancellation provisions.
