Uniforms from other universes.
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 to denote rank, this version used gold bars behind a silver Starfleet delta as well. (TNG: "Parallels")
Uniform changes resulting from a temporal event.
Earth destruction timeline (2153-2165)
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 unto 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")
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")
Uniforms from possible futures.
Slipstream crash timeline (2375-2390)
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.
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")
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...")
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:
The yoke of the uniform featured a small strip of division color extending from the right side and coming 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 Starfleet uniforms worn during Star Trek: The Original Series were designed by William Ware Theiss, who returned to design the Star Trek: The Next Generation uniforms (which were further adapted into future versions on DS9, VOY, and the TNG-era films by Robert Blackman).
