Starfleet uniform ( 2370s ) In 2373 , the standard Starfleet uniform was again modified , maintaining the same basic shape and division colors , but reversing the colors on the shoulders and turtleneck . The blue - grey shoulder area was now quilted with vertical stitches . The division colors were also displayed on each wrist as a colored hoop . A succession of other Starfleet uniform s based upon this modification were also phased into service during this time . As Data ' s uniform was not liquified when he ruptured the coolant tank on the , it appears these uniforms were created with non - organic fibers . ( ) Standard duty uniform . While the standard , two - tone duty uniform introduced in the late 2360s remained in service ( at least ) until 2373 , it was phased out of regular use aboard Starfleet vessel s and space station s beginning in 2373 . Although the new duty uniform retained the same basic structure and style of the last standard duty uniform , the yoke / shoulder area usually displaying division colors was given a standard , blue - gray color and quilted . Cuffs were also added to the uniform , bearing a stripe of corresponding division color . The uniform shirt and undershirt were also modified . ( ; ; ) Captain ' s variants . With this new wave of duty uniforms , so too came minor variants available to commanding officers . Similar to the so - called " captain ' s jacket " variant worn in the 2360s , a new vest or waistcoat was introduced aboard starships and space stations . Bearing the same gray , quilted yoke as the duty uniform ( extended lower , below the combadge ) , this sleeveless , low - necked vest allowed the wearer a more casual appearance . ( ; ) In addition to the vest , a more formal uniform was also available to commanding officers . Featuring only minor differences from the standard duty uniform , a variant uniform without cuffs and bearing a more formal collar was also in use as early as 2373 . ( ) Uniform undershirt . When compared to the previous design , the mock turtleneck shirt worn beneath the jumpsuit uniform was made of a heavier material , now displaying one of three division colors and opening in the front from a prominent closure . Beneath this , a blue - gray tee , or sleeveless tee , was worn , similar in style to the undershirt of the previous design . ( ; ) Flag officer uniform . First appearing in 2374 , Starfleet issued a uniform for flag officers such as admiral s reflecting the new duty uniform . Again retaining the same basic form as the previous style , the next generation of flag officer service uniform incorporated the adjusted color scheme and quilted yoke . The cuffs were wider than present on the standard uniform , displaying admiral ' s rank insignia . A belt was also introduced to the uniform , with either a plain gold rectangular buckle or an oval buckle displaying the Seal of the United Federation of Planets . ( ; ) Dress uniform . Again coinciding with the alterations made to the duty uniform , two distinct variations on the Starfleet dress uniform were introduced . Type A . The first , used around 2374 , closely resembled the preceding style of dress uniform , a standard two - tone long jacket and black trousers . New to this version , which retained the previous coloration of black with one of the three division colors , was the quilted yoke , cuffs with a gold band , and a black belt displaying the seal of the United Federation of Planets . The gold trim along the collar was widened to three parallel gold bands , with the middle band retaining the broken style of the few previous dress uniform styles , while the outer bands were solid . ( ) Type B . In 2375 , the second dress uniform variant was introduced , this time a stark departure from previous styles . Throwing out the old color scheme and long jacket , the new style favored a white , short jacket with gold trim and a quilted gray center section , worn over black trousers which were also trimmed in gold . Division colors were less prominent than in the preceding style , appearing as piping around the collar and wide bands on the cuffs and side seams of the trousers . While this uniform was standard to all duty officers , captains and flag officers wore white in place of blue - gray in the center section . Flag officer s had a wider cuff braid with a solid white line running through it upon which rank insignia was affixed . Members of the Starfleet band at the Riker - Troi wedding worn a solid gray uniform , which featured a longer , looser jacket than the standard uniform . The gold and division color trim on the standard jacket was replaced with white , and the collar , now distinguished by white trim where it meet the shoulders , sported a thick band of white running the center of it where rank was displayed . The division color strip on the pants was also white . ( ; ; ) Desert robes . For harsh or desert conditions , specialized robes were worn to protect against sun light and provide comfort in hot and humid conditions . Consisting of off - white - colored robes and hoods , pants and short - sleeve shirts , trimmed with division colors , this particular uniform served when the standard duty uniform may have proved uncomfortable or inappropriate for some environments . Specialized boots were also part of the desert uniform , also off - white , with treads better suited to mountainous or more rugged terrain . ( ) Combat uniform . Retaining the same general appearance as its predecessor , the uniform used by Starfleet personnel in combat situations was a black combat jacket with a division color stripe running across the chest . The division color mock turtleneck was worn beneath the rubber - like body armor . ( ) Utility uniform . As with the previous generations of Starfleet uniforms , a plain , operations mustard - colored jumpsuit used by technicians and utility workers was available as late as 2379 . ( ) Cadet uniform . Some time around 2372 , a corresponding alteration was made to the uniform worn at Starfleet Academy and by Starfleet cadet s serving aboard starships . While essentially the same design as the preceding style – gray jumpsuit with division colored shoulders – quilting was again added to the yoke as were cuffs bearing division colors . Instead of being a one - piece uniform , however , it was split , now sporting a gray mock turtleneck beneath . As with the earlier style , the uniform was gray ( rather than black worn by officers ) and featured pockets running down the trousers . ( ) Section 31 uniform . In use since the mid - 22nd century , the distinct , black uniforms worn by operatives involved with Starfleet ' s secret organization Section 31 remained basically unchanged in the 2370s . Made from a black , leather - like material , the Section 31 uniform consisted of a long , black coat worn over a black mock turtleneck tunic and black trousers . ( ) Given Section 31 ' s autonomy , secrecy and organization , it probably has no standard duty uniform ; at least none that Starfleet can critique . Other uniform features . Depending on their various circumstances and traditions , some Starfleet officers were allowed to augment their uniforms with the addition of cultural items . Klingon Starfleet officer Worf wore a baldric displaying various family emblems throughout his tenure in Starfleet . ( ) Bajoran Colonel Kira Nerys was allowed to retain her culture ' s traditional earring when given a field commission of commander . ( ) Ferengi cadet , and later officer , Nog wore a headdress traditional among his people . The headdress matched the color and texture of the shoulder material on his uniform . ( ) Medical doctor s and other scientist s also adorned their Starfleet uniforms differently than other officers , wearing lab coats over their standard uniforms . ( ) Appendices . Background information .
