3180s
Fast forward nearly eight hundred years, and we get to miss out on an awful lot of Starfleet uniforms. But we do get a glimpse of the very futuristic fashion of the 32nd Century in Discovery, and the future is…very grey. The most businesslike of all the uniforms we’ve seen so far, this tunic maintained division delineation through a large stripe running vertically down an officer’s right side—now adding specifically white for Medical personnel, on top of the red, gold, and blue for Command, Operations, and Science.
Interestingly enough, security officers, usually roped in with Ops, get their own uniform variant, presumably because tactical maneuvers in a bulky suit were annoying. Featuring a dark blue honeycomb-padded section across the arms and upper torso, this variant was filled out with a similarly grey-toned jumpsuit.
