Casual duty attire was informal clothing worn instead of a standard uniform while on duty.
On some Starfleet vessels, certain crew members were granted permission, at the captain's discretion, to wear casual duty attire while serving on board. This diversion from the standard uniform code was typically granted to senior officers in specialized positions. (TNG: "Chain of Command, Part I")

T'Pol's uniform
In 2153, Enterprise NX-01 science officer T'Pol resigned from the Vulcan High Command. (ENT: "The Expanse") As she was no longer permitted to wear her former uniform as a civilian, she opted to don brightly colored, tight-fitting jumpsuits while on duty. (ENT: "The Xindi") After T'Pol accepted a commission to commander in 2154, her civilian jumpsuits were modified to include division coloring, rank insignia, and other details consistent with standard uniforms of the period. (ENT: "Borderland") T'Pol continued to wear variations of her civilian jumpsuits until at least 2161. (ENT: "These Are the Voyages...")

Captains had a choice of relaxed clothing to wear when on duty, in the form of a wraparound tunic. James T. Kirk favored two green variations. Charles Evans also wore a beige version of this tunic, though where it originated from is unknown. (TOS: "The Enemy Within", "Charlie X", "The Doomsday Machine")
The captain of the USS Defiant also had a green tunic when the ship disappeared through a spatial rift in 2268, to reemerge in the mirror universe in the year 2155, where Jonathan Archer found the tunic in his quarters and wore it himself. (ENT: "In a Mirror, Darkly, Part II")
Mid 2270s
Sulu in a wraparound tunic
This wraparound tunic was worn by Lieutenant Commander Hikaru Sulu shortly before the USS Enterprise departed drydock to confront V'ger and during Admiral Kirk's briefing to the entire crew. This tunic had short sleeves and was worn over a black undershirt. Epaulets denoting rank were found on the tunic. Pants matching the color of the jacket were also worn. A metal Starfleet emblem found near the waist on the jacket was used to close it over the undershirt. (Star Trek: The Motion Picture)
Bomber jacket

In keeping with the Starfleet practice of allowing officers of command rank to wear a less formal variant of the uniform, starting in the late 2270s command officers were given the option of wearing a suede leather bomber jacket version of the uniform. This was worn over the department color turtle neck. (Star Trek III: The Search for Spock, Star Trek IV: The Voyage Home, Star Trek V: The Final Frontier)
24th century
Deanna Troi's duty attire
Between 2364 and 2370, Deanna Troi frequently wore casual, nonuniform attire while on duty as ship's counselor, as an alternative to a standard Starfleet uniform. She primarily favored unitards in a variety of colors. (TNG: "The Naked Now" – TNG Season 6) Occasionally, she wore a turquoise variant with a long skirt. (TNG: "The Survivors")
While serving under Edward Jellico in 2369, she was ordered to wear a standard uniform while on duty. (TNG: "Chain of Command, Part I") After Jellico's order, she wore a traditional uniform almost exclusively during the rest of her posting aboard the USS Enterprise-D. (TNG Season 6 – Star Trek Generations)
Captain's variant
By 2368, Starfleet had a uniform variant available to commanding officers in service aboard starships, consisting of a red command division suede jacket featuring banded cuffs and either leather or fabric black shoulders. Less formal than the standard duty uniform, this "captain's jacket" was a more casual dress option, with trousers reminiscent of the previous Starfleet uniform. (TNG: "Darmok", "Ensign Ro")
