(coexisting on another dimensional plane)
Service members of Starfleet wore a common uniform that facilitated the individual's needs as soldiers of the Terran Empire. The uniforms were used to display an officer or crewman's current status, rank, divisions, and decorations awarded over the course of their service. Throughout the history of the Starfleet uniform, there were distinctive difference between commissioned and enlisted personnel as well as male and female service members.
Officers and crewmembers wore Starfleet uniforms and rank insignia similar to the counterpart universe Starfleet. The uniforms and ranks, while similar, displayed some striking differences, such as standard sidearms (phase-pistols in the 2150s and phasers from the 2160s onward) and daggers, military decorations, and shoulder braces or sashes. Some officers wore a Sam Browne belt.
During the 22nd century, Starfleet uniforms were similar to their counterpart universe's Earth Starfleet. In 2155, the standard officer uniform was a navy blue jumpsuit with division color (red, aqua, or gold) stripes at the shoulders. The insignia of the Terran Empire was worn on a patch on the right shoulder, and an assignment patch based on the posting of the officer was worn on the left shoulder. Decorations and medals were worn on the left breast and shoulder brace. Female uniforms were simpler, with a pants and top combination with the same arrangement of markings, but a bare midriff. Rank insignia were displayed on epaulets. (ENT: "In a Mirror, Darkly", "In a Mirror, Darkly, Part II")

Decorations and medals were worn on the left shoulder. Captains worn a gold chest piece, gold shoulder pads and a gold thick belt. The tactical gear was more heavily protected than the prime universe.
By 2267, the uniforms were similar to those discovered aboard the USS Defiant in 2155, but were altered to allow for some of the exceptions mentioned below. (ENT: "In a Mirror, Darkly, Part II"; TOS: "Mirror, Mirror"). In 2267, the standard officer uniform was black trousers with a division color (red, blue, or gold) tunic. The insignia of the Terran Empire was worn on the right breast. Decorations and medals were worn on the left breast.

The Terran Empire uniforms in Star Trek: Discovery were designed by Gersha Phillips, who explained they were intended to echo the assymetrical appearance of the Star Trek: The Original Series uniforms. She also wanted it to be in keeping with the aesthetic production designer Tamara Deverell had settled on for the Terran Empire, which is heavily influenced by the art deco movement as well as brutalist architecture. Phillips revealed that she had designed a red medical uniform planned for the show, "which would've been kinda cool."  This design eventually appeared, worn by Hugh Culber, in "Terra Firma, Part 1" and "Terra Firma, Part 2".
