The duty uniform consisted of a black undershirt, and a colored overshirt featuring the officer's division color and the Starfleet insignia. Rank stripes were displayed on the sleeves. Charcoal grey pants and boots were issued with the uniform.

This uniform was only used aboard starships, and not at Starfleet Command or on Starbases.

By 2263, Starfleet introduced a new style. Much like the Type A uniforms, the standard duty uniform consisted of a collared shirt with a division color, yellow, blue, or red, a pair of black pants and black boots. Unlike the previous design, it lacked the detail of the sewn-in Starfleet insignias in the fabric.

This design of Starfleet uniforms was used from 2265, to the early 2270s.

The top was a long-sleeve, division-colored tunic, which bore rank insignia, displayed as sleeve stripes, and an assignment patch on the left breast. The tunics had a black collar with a V-shaped bottom. Black pants were worn with black boots.

Crew members also had the choice to wear a one-piece uniform that continued down into a miniskirt over matching high cut shorts, worn with black boots. It had two variations, one with no sleeves and one with full sleeves. Without the sleeves. They did not display the user's ranks.

A skant uniform was available with the new style in 2263. It had a shorter black collar, was division colored and had a grey swatch on the waist. It could be worn over grey trousers.

A short-sleeved "smock" tunic was often worn by medical personnel. It gave the user more free use of their hands than the standard long-sleeved tunic.

The uniforms used on starbases were a two-piece outfit with light grey pants and jackets with division colored accents on the shoulder, back and two stripes on the arms. It was worn with a black belt.

Flag officers serving on starbases wore a two-piece outfit with light grey pants and jackets with a dark grey/black shoulder color and had rank insignia on both arms as well as at the neck.

Fully commissioned officers working at Starfleet Headquarters, Starfleet Academy and archive facilities, and other ground installations wore a charcoal black standard uniform similar to cadet dress uniforms; instructors at Starfleet Academy also wore this uniform. Barracks officers and shuttle officers wore a variation of this uniform which included a black cap.

Admirals and flag officers wore a cream-and-grey uniform for regular, daily duties. Admiral Christopher Pike wore one such uniform when transferring command of the Enterprise to James T. Kirk. Starfleet Command Admirals such as Richard Barnett wore a silver tunic without any division colors while serving on the Starfleet Academy Board in 2258. Other flag officers wore this uniform with a cap of the same design, featuring the Federation emblem on the front.

Cadets wore a red jumpsuit and jacket with a stand collar over a red turtleneck-like sweater; men and women wore pants while some women wore skirts. On both male and female designs, the Starfleet insignia was displayed prominently on the collar of the jacket.

The flag officer uniform was a two-piece outfit with dark gray pants and a white and dark gray flared jacket featuring a high collar. Rank was shown by both epaulets and sleeve stripes, and a gold Starfleet Command pin was worn on the chest.

For formal gatherings, Starfleet personnel wore gray or brown uniforms with high collars accompanied by a traditional peaked cap with the Starfleet emblem. Rank insignia was displayed by the standard stripes on the cuffs and by black lozenges on the shoulders. A skirt was also available.

Officers wore flight suits while traveling in shuttles. They were gray overalls worn over the Duty uniforms. They had transparent yokes to show the division color, and the insignia was emblazoned on the upper arms.

Starfeet officers had access to survival gear as part of the equipment stored in escape pods. This gear featured a dark blue jacket with the officer's division color on the shoulders, with matching gloves, boots, and pants.

Wetsuits came in two varieties: male crewmembers wore grey wetsuits with division colored piping, while female crewmembers wore division color ones with grey piping. These uniforms were equipped with engines placed on the ankles to propel the user through water at high speeds.
