American costume designer (1922–2021) who designed the costumes for the first four Star Trek films, including the maroon Starfleet uniforms introduced in The Wrath of Khan.
Robert Fletcher (1922–2021) was an American costume and set designer with a long background in theatre, opera and ballet before he came to Star Trek.
He designed the costumes for Star Trek: The Motion Picture, Star Trek II: The Wrath of Khan, Star Trek III: The Search for Spock and Star Trek IV: The Voyage Home. His pale uniforms for the first film were replaced in the second by the maroon, naval-style Starfleet uniform, which stayed in use for the rest of the original cast's films.
Fletcher also set the look of film-era Klingons and Vulcans, giving each culture its own fabrics, jewellery and armour, and his designs were referenced by later series.
