Design

For Khan and his followers, Fletcher created a strong contrast with the highly organized Starfleet uniforms; his idea was that the exiles' costumes were made out of whatever they could find. Fletcher said, "My intention with Khan was to express the fact that they had been marooned on that planet with no technical infrastructure, so they had to cannibalize from the spaceship whatever they used or wore. Therefore, I tried to make it look as if they had dressed themselves out of pieces of upholstery and electrical equipment that composed the ship." Khan's costume was designed with an open chest to show Ricardo Montalbán's physique. Fletcher also designed smocks for the Regula I scientists, and civilian clothes for Kirk and McCoy that were designed to look practical and comfortable.
