From Star Trek: Theurgy Wiki
Starfleet uniforms were uniforms worn by individuals serving in the Federation Starfleet, originally a United Earth organization. These uniforms facilitated the wearers' needs as both scientists and researchers, as well as Starfleet's military role. Wearers were expected to abide by the Starfleet dress code, though special exceptions were sometimes made for certain aspects of an individual's cultural heritage, such as Worf's Klingon baldric and Nog's Ferengi headdress as well as Ro Laren's (and briefly Kira Nerys') earrings.

These were the Starfleet Uniforms as of 2381 in Starfleet. Like all ships, the USS Theurgy had a specific dress code for on-duty officers. The standard duty uniform was a three piece ensemble consisting of pants, colored undershirt (department specific color), and jacket. An optional skirt was permitted for female crew if they wished.
