John Myles Milton Bright (born 7 March 1940) is a British costume designer. He is particularly known for his collaboration with Jenny Beavan on creating the costumes for Merchant Ivory Productions, and as the founder of Cosprop costume house.
Bright has been nominated for the Academy Award for Best Costume Design six times, winning for A Room with a View (1985).
In 2022, Bright set up The Bright Foundation, an arts education charity to provide access to the arts for children living in and around Hastings, East Sussex. The organization operates out of two venues, including the Barn Theatre and Museum and the Benbow Arts Space. The former venue features a barn-converted children's theatre and workshop studio, alongside a museum and exhibition space showcasing Bright's collection of period toys, puppets, and theatre sets, while the latter venue is located in the heart of St Leonards-on-Sea and is a creative learning hub dedicated to the art of filmmaking, where young people can discover their passion, develop skills and begin their journey into the film industry. The Foundation offers free access to both venues to schools and community groups.
