In the TOS, set in the 2250s to the early 2270s, the standard duty uniform consists of a long-sleevedtunic with rank insignia sleeve stripes, color-coded by division (gold = command, red = operations, blue = sciences/medics), black undershirts, black pants, and black boots. Captains wore a green-yellow wraparound tunic similar to East Asian clothing. Female uniforms were of a single tunic/miniskirt combo with pantyhose.
In the episode Mirror, Mirror, the Terran Empire uniform is similar, replacing the Starfleet delta insignia with the sword-and-globe imperial insignia and adding a gold sash belt. Female uniforms consisted of a tank top, black midriff undershirt, miniskirt, and thighhigh boots.
The TNG, set in the 2350s, has a different version of the uniform: a black jumpsuit with the assigned color of division in front (red = command, gold = operations, blue = sciences), Starfleet insignia on the left breast side, rank insignia on the right collar.
