Starfleet uniform (2370s-early 2380s)

In 2373, the standard Starfleet uniform was again modified, retaining the same basic shape and division colors from the previous design, but reversing the colors on the shoulders and turtleneck. The -gray 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 uniforms and a new combadge were also phased into service during this time and used concurrently. By 2380, the blue-gray version continued to be used aboard the , , and Starbase 25, while a newer uniform with a different combadge was worn by personnel aboard and vessels. () 
In addition to these uniforms, earlier versions of the standard duty attire were still used among some Starfleet officers during this time. ()
As Data's uniform was not liquefied 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 vessels and space stations 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. (; ; )

==== Transitional variant ====
By 2380, the greenish-blue division coloring of this era's sciences uniform was seemingly phased out in favor of a brighter shade of blue. ()
=== Type B ===
This version, introduced by 2381, featured an extension of the gray shoulder material down the center of the jacket to mid-chest. To either side along the shoulder area, a black stripe with division-colored piping ran across the torso, over the arms, and around the back. This design would eventually inform the look of the division colors at the shoulders of the standard of the mid-2380s. ()
=== 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 new uniform for flag officers, such as admirals, reflecting the new duty uniform. 
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 jacket was longer and edged in gold, and the tunic displayed rank insignia on both sides of the collar. The cuffs were wider than present on the standard uniform, displaying admiral's rank insignia on both sleeves. 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 officers 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 wore solid gray uniforms, which featured longer, looser jackets than the standard uniform. The gold and division color trim of the standard jacket was replaced with white, and the collar, now distinguished by white trim where it met 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 sunlight and provide comfort in hot and humid conditions. 
This particular uniform consisted of white hooded robes, with off-white pants and short-sleeve shirts trimmed with division colors and was used when the standard duty uniform might 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 cadets 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 distinctive 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 high level of autonomy, secrecy, and their overall lack of protocol, it was more likely that they had no standard duty uniform - at least none that Starfleet could 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 doctors and other scientists also adorned their Starfleet uniforms differently than other officers, wearing lab coats over their standard uniforms. (; )

===Background information===
The Starfleet uniforms introduced in the 2370s were designed by TNG, DS9, and VOY veteran costume designer Robert Blackman, based upon William Ware Theiss's designs from The Original Series.
In an audio commentary for , Jonathan Frakes revealed that he hated wearing this style of Starfleet uniform for the TNG Star Trek films.
===Apocrypha===
Though these uniforms were not seen in canon until 2373, the fourth and final issue of the IDW Publishing miniseries Star Trek: Spock: Reflections shows Picard wearing this uniform in 2372, after Spock had taken Kirk's body from Veridian III and re-interred it at the Kirk family farm in Iowa.
