Kym Barrett, costume designer, said that she defined the characters and their environment by their costume. For example, Reeves's office costume was designed for Thomas Anderson to look uncomfortable, disheveled and out of place. Barrett sometimes used three types of fabric for each costume, and also had to consider the practicality of the acting. The actors needed to perform martial art actions in their costume, hang upside-down without people seeing up their clothing, and be able to work the wires while strapped into the harnesses. For Trinity, Barrett experimented with how each fabric absorbed and reflected different types of light, and was eventually able to make Trinity's costume mercury-like and oil-slick to suit the character. For the Agents, their costume was designed to create a secret service, undercover look, resembling the film JFK and classic men in black.
