The wardrobe section was the department on the USS Enterprise responsible for managing clothing under the command of the quartermaster.
In 1969, James T. Kirk said to Spock (referring to Captain Christopher), "Why don't you have the quartermaster issue him something more suitable?" (TOS: "Tomorrow is Yesterday")
In 2269, Spock requested a Vulcan desert soft suit and boots, as well as a small selection of street wear and carry bag, circa 8877 Vulcan year for his journey back in time. (TAS: "Yesteryear")
