Beginning in the year 2366, a new uniform variation was introduced to officers serving in Starfleet. Retaining the same, distinct two-tone style as before, the newer version featured a higher, more formal collar. Division color piping was relocated from the yoke to the top of the collar, resulting in a flat black appearance. This alteration was introduced to senior officers only at first, but was ultimately trickled down to lower-ranking crewmembers by 2368. Most wore a two piece belted version. It continued to be used alongside the next redesign until 2374.

The rank pips were on the right color. The combadge remained on the left breast.

While all officers aboard starships wore the same basic uniform, some crew members wore a tighter, non-belted version.

Starfleet had a uniform variant available to commanding officers in service aboard starships, consisting of a red suede jacket featuring banded cuffs and either leather or fabric black shoulders. It was worn over a grey long sleeved shirt which also had black shoulders. Black pants and boots were worn with the jacket.

The provisional uniform was worn by crewmen such as acting ensigns. It consisted of a grey turtleneck with matching trousers. The collar and shoulders were a dark charcoal gray and ribbed. It was worn with an entirely silver-colored combadge.

During the late 2360s, cadet uniforms consisted of a black, two-piece jumpsuit with division-colored shoulders. It had a low collar, trimmed in black, and had no rank insignia. It had several large pockets running down the trousers.

By 2368, the cadet uniform featured a high collar, with rank (or student year) insignia being added shortly thereafter. It had several large pockets running down the trousers.

With the alteration of the standard duty uniform in 2366, a new wave of uniforms for flag officers and admirals came into service. This alteration featured a long service jacket and trousers, with black shoulders, similar to the standard duty jacket.

It was marked by a V-shaped black cutout, trimmed in gold. The rank insignia were enclosed pips worn on either side of the uniform collar, as well as displayed on both sleeves with four widely spaced, thin gold braid stripes ending at the cuff.

In 2369, a new flag officer's uniform was introduced. Retaining the familiar long jacket and trousers, this newer version was simpler, abandoning the distinctive black wedge cutout from the previous design for a gold-trimmed closure running down the front of the uniform. The sleeves of the uniform were also modified, now bearing the rank insignia within a wide, black cuff.

This version was ultimately retired from service in the year 2374.

Starfleet personnel were issued a standard dress uniform for diplomatic events.

In 2367, the dress uniform was again modified, this time removing several inches of material at the bottom, bringing the bottom of the jacket to mid-thigh just below the hands. A small section of the gold trim that ran vertical from the end of the top opening to the yoke was also removed, leaving only the trim above the rank insignia that ran around the collar.

By 2365, a new version of the dress uniform was available. It introduced rank insignia to the right shoulder and swapped the single gold braid for two narrower braids running parallel to each other (one gold, one silver), which together were the same thickness as the original.

The gold braids also no longer extended below the black material that covered the shoulders from the yoke upwards.

Chief Medical Officers had the option to wear a light blue lab coat over their sciences division uniform.

During surgical sessions, scrubs were provided to doctors, consisting of burgundy-colored gowns and caps. Medical personnel also wore rubber-like surgical gloves during more intensive medical procedures and surgeries.

In the mid-2260s, utility jumpsuits came in division color. Some versions had embroidered writing and insignia on the left breast. The jumpsuit had medium length sleeves and was worn open in the front, sealing at the waistline. A standard black undershirt was worn underneath.

Scientists serving at outpost stations during the 2360s wore a gray uniform with white trim. It was worn by Federation anthropologists working with Starfleet.
