Starfleet uniform (alternate)

Multiple realities
(covers information from several alternate timelines)

Other versions of the Starfleet uniform from various alternate timelines and parallel universes.

Parallel universes

Uniforms from other universes.

See: Starfleet uniform (mirror)

Quantum incursions (2370)

One of the parallel universes experienced by Worf during his quantum incursion had a variant of the 2366 Starfleet uniform. Along with the use of pips on the collar, this version also used gold bars behind a silver Starfleet delta to denote rank. (TNG: "Parallels")

This same uniform, sans pips, is seen in Barash's illusion.

Alternate timelines

Uniform changes resulting from a temporal event.

Earth destruction timeline (2153-2165)

Commander Malcolm Reed in an alternate 2165

In an alternate timeline where Jonathan Archer was infected with interspatial parasites, Starfleet continued the use of their 2151 uniforms up until 2165. They did not adopt the addition of personnel names and Starfleet membership patches onto the uniform by 2161 as they did in the regular timeline. (ENT: "Twilight")

Federation-Klingon War timeline (2344-2366)

In the alternate timeline created by the disappearance of the USS Enterprise-C in 2344 and the subsequent outbreak of the Second Federation-Klingon War, the Starfleet uniforms were similar to the ones worn in 2366 in the prime timeline, but had enclosed collars and black cuffs. Phasers were worn at all times in silver belts with an offset buckle, in the shape of a gold Starfleet insignia; enlisted crewmembers had one resembling a Sam Browne belt. (TNG: "Yesterday's Enterprise")

This uniform appeared to have existed in the regular universe, as Geordi La Forge wore it in the last scene of "Yesterday's Enterprise". It is most likely that wardrobe simply forgot to have LeVar Burton change between shots.
The belt buckle resembles the fastener on the wraparound tunic in the late 2260s.
Seven years later in the prime timeline, with the outbreak of the Dominion War, Starfleet officers would also wear phasers on their uniforms while in combat, though without any extra belts.

One of the silver belt-harnesses was sold off on the It's A Wrap! sale and auction on eBay. [1]

Subspace inversion timeline (2372 - early 25th century)

In a timeline where Captain Benjamin Sisko was killed on the USS Defiant during a subspace inversion of the wormhole, and the Dominion War apparently never happened, Starfleet never adopted the 2370s uniform. This timeline did adopt the 2390s uniform seen in other alternate futures. (DS9: "The Visitor")

Future timelines

Uniforms from possible futures.

Slipstream crash timeline (2375-2390)

In a 2390 where the USS Voyager was destroyed, the uniforms had not yet changed from the 2370s version, although they did accept a new combadge. (VOY: "Timeless")

Starfleet uniform (2390s-2420s)

Several alternate future timelines show this uniform to be in service in the mid to late 2390s, with the combadge coming into service in by least 2390. The actual uniform used in the 2390s was different, but had a similar combadge and similar placement of the rank insignia.

Duty uniform

The duty uniform consisted of a division color double-breasted jacket with, like the uniform in the 2230s, black piping running across the yoke, and black pants. Rank was displayed in a series of pips on the upper right breast pocket, just above the piping. (TNG: "All Good Things..."; VOY: "Endgame"; DS9: "The Visitor")

Cadet uniform

Cadets wore uniforms similar to the duty uniform but instead of a division color, the jackets were gray, lacking any apparent rank insignia to indicate their class. (VOY: "Endgame")

If the class shown was a freshman class, they may not have possessed a rank indicator.

Admiral's uniform

The uniforms worn by flag officers were similar to the standard uniform with the exception of gold trim running down the edge of the jacket over the right breast and on the cuffs, though the 2369 version was still in use in the "anti-time future". (VOY: "Endgame"; TNG: "All Good Things...")

Riker may simply choose to wear an old uniform, since Admirals have been shown to have a wide latitude with their uniforms.

29th century

The uniforms worn by Starfleet personnel during the 29th century reflected the template of previous generations, but displayed advances in style and a shift in division color-coding.

Standard duty uniform

Adopted sometime during the 29th century, the standard duty uniform worn aboard such Starfleet starships and timeships as the USS Relativity appeared very similar to those in service during the 24th century. Consisting of a single-piece black jumpsuit, the duty uniform featured a high, mandarin collar displaying rank insignia with a Starfleet insignia/communicator badge worn on the left breast.

The uniform was distinguished by a prominent swath of division color extending diagonally from the left side of the collar down the right sleeve. This swath consisted of a quilted or patterned material and, as in the past, was coded in at least three division colors denoting department of service:

Blue – Command division
Brown-Orange – Operations division
Grey – Sciences division

The yoke of the uniform featured a small strip of division coloring that extended from the right side and came to a point on the left shoulder. The right side featured an identical strip in black. The collar of all three divisions was trimmed in white. (VOY: "Future's End", "Relativity")

The "future" Starfleet uniform was designed by Robert Blackman, reflecting the designs of William Ware Theiss from Star Trek: The Original Series and Star Trek: The Next Generation. It made its first appearance during the episode "Future's End" though differed slightly from its more prominent appearances in "Relativity". The uniform worn by Captain Braxton in "Future's End" featured a slightly different collar (dipping to the left) and was brighter-blue. The jumpsuit portion may have also been red or burgundy in color, though the black may have been affected by the interior lighting of the Aeon. Division colors are inferred from on screen evidence, not from dialogue.

Examples of rank insignia

Ensign

Lieutenant

Captain

Only three rank insignia types were observed in the episode "Relativity". More are likely to exist, but they remain conjectural.
