worn with charcoal slacks – which appeared black on camera – only by men. While women wear trousers in the pilots, most female Starfleet personnel wear more revealing costumes per request from NBC; Grace Lee Whitney suggested miniskirts. William Shatner observed that Star Trek, "to the appreciation of all the men on the set, in fact all around the world, would boast the shortest skirts on women of any regular series on television". Miniskirt-length dresses (of the same materials and colors as the shirts) with cheer briefs and dark tights were worn by the women. Black boots were worn by both sexes. Nichelle Nichols did not believe that the miniskirts were unusually short or revealing: Once the series went into production, use of the jackets on landing parties stopped, even in inclement weather (e.g. "Mudd's Women"). On certain occasions, the characters would wear dress uniforms (TOS: first shown in "The Menagerie" and later used in "Court Martial", "Space Seed", "Journey to Babel", and "The Savage Curtain") that are made of a shinier fabric, presumably a polyester satin, and are decorated with gold piping and colored badges that vary depending on rank. Montgomery Scott's dress uniform, especially as seen in "The Savage Curtain", includes a Scottish tartan. Specifically, it is the tartan of the Clan Scott, one of Scotland's oldest clans. Jumpsuits in the same colors with black undershirts were also worn, mostly by background characters. Beginning with the first production episode "The Corbomite Maneuver", the department colors were slightly altered from the pilot versions: command and helm personnel wear gold shirts; operations, engineering and security personnel wear red; and science and medical personnel wear blue, all with black collars and undershirts. The most commonly used Command Section shirts were actually chartreuse-green in color, but they appeared to be a golden-yellow color both under the lights used on the set and in the post-development film stock. In later series, the gold color was canonized in dialog. However, some uniforms – the alternate shirts worn by Captain Kirk, and the Command Section dress uniforms – were made of a different material which, while the same color, showed up as chartreuse-green even under the lights and when photographed. The green shirts (seen in TOS: "The Trouble with Tribbles", "Charlie X" and "The Immunity Syndrome") may have the rank stripes on the sleeves or on the collar (TOS: "The Enemy Within"), and always feature
