In the mid to late 2230s, a new Starfleet uniform design was introduced in place of the previous design, which had been used since the early 2230s. There were at least three standard colors for the new uniform design: gold (command), copper (operations/engineering), and silver (science). (DIS: "The Vulcan Hello")
This version of the Starfleet uniform was in use on the USS Shenzhou, USS Europa, USS Yeager, USS Discovery, USS Glenn, and USS Gagarin. (DIS: "The Vulcan Hello", "Battle at the Binary Stars", "Context Is for Kings", "Choose Your Pain", "Si Vis Pacem, Para Bellum")
Standard duty uniform Edit
The standard duty uniform was a Federation blue jacket and pants with raised division-colored striping encircling the shoulders (five stripes for men, four for women) and down the side seam of the jacket and pants (six stripes for all uniforms) and raised division-colored Starfleet deltas printed on the flanks of the jacket to the front of the division stripes, continuing onto the upper hip of the pants. The jacket featured a split cowl collar with a division-colored zipper closure running slightly diagonally from the center line of the jacket at the bottom to the right side of the collar. The pants featured front thigh pockets also with division-colored zippers, and an apparent front fly. The shoulders, knees, and elbows had distinct textured fabric sections.
Division-colored metallic Starfleet delta badges were worn on the left breast. They featured a division insignia and rank pips carved into the badge; the reverse carried the wearer's name and serial number. (DIS: "Into the Forest I Go") The uniform included shin-high boots, with division-colored trim around the edges of the soles, and metallic division-colored Starfleet-delta-shaped boot clamps. (DIS: "The Vulcan Hello", et al.) This uniform was in use by at least 2249. (DIS: "Battle at the Binary Stars")
Long sleeve style Edit
The flag officer uniform was very similar to the captain's variant of the standard duty uniform, but with the additional narrower shoulder striping also on the shoulder fabric to the outside of the standard stripes. Of note is that the colored stripes on the outside shoulder ran parallel to those on the inner shoulder and the main stripes. This is in contrast to the textured fabric on the outer shoulder of the standard and captain's uniforms on which the textured stripes intersected the main division-colored stripes. Flag officers also wore a different badge: one with the Starfleet delta encircled by laurel leaves. (DIS: "Battle at the Binary Stars")
Short sleeve style Edit
Worn by some crewmembers aboard the Shenzhou and the Discovery, this alternate version of the standard duty uniform was worn in all three divisions. The differences were a larger belt-like sash around the waist and short-sleeved arms. It was worn on the bridge and in other sections of the ship. (DIS: "The Vulcan Hello", "Context Is for Kings")
Combat uniform Edit
The uniform of this time had a tactical gear set that had a vest over a one-piece variant of the standard uniform which replaced the metallic piping with more conspicuous compression panels. The vest featured a flashlight on the shoulder and a round black badge with a silver Starfleet symbol in the middle and the text "Starfleet Command" above it. (DIS: "Battle at the Binary Stars")
Excursion gear Edit
Flight suit Edit
Thruster suit Edit
The Starfleet uniforms of this time had a thruster suit for space walks and missions outside of the ship. It was a white space suit. The officer would wear a gold tinted undersuit and cap underneath their space suit. (DIS: "The Vulcan Hello")
Medical uniform Edit
Patient wear Edit
During sporting activities and exercise, crew members wore black T-shirts with the Starfleet delta on the sleeves and black sweatpants, with accompanying footwear. On the Discovery, the T-shirts had the text "DISCO" on the front. (DIS: "Lethe")

In Bryan Fuller's original conception of the series that became Star Trek: Discovery, the Starfleet uniforms were to have been a subdued version of the primary colors from Star Trek: The Original Series' Starfleet uniforms. (Entertainment Weekly, issue 1476, p. 27) The uniforms ultimately seen in DIS were designed by Gersha Phillips, who opined that while the original Starfleet uniforms were "great costumes, I just don't think they resonate anymore, and they don't resonate in 2259." She expressed admiration for the Star Trek: Enterprise jumpsuits, describing them as "grounded in reality [...] I like the idea that they wear almost like a naval uniform or a NASA uniform." 
The Starfleet insignia badges were made in Toronto, Canada, by creating wax models from 3D prints, then producing plaster molds for silicon bronze to be poured into. The resultant bronze badges were subsequently polished and plated by a jeweler to give them the custom colors for Star Trek: Discovery. ("Star Trek Exhibition" at "Si Vis Pacem, Para Bellum" screening, Millbank Tower, London, UK, 5 November 2017) A collection of four of these badges were featured at Star Trek: The Exhibition in Blackpool, UK, and are now on a world tour.
The black security badges were seen on screen only once, during the sequence where Burnham and her fellow prisoners are first being escorted to the mess hall after just boarding Discovery. They would not be seen again until the "bonus scene" from DIS: "Will You Take My Hand?", as shown at WonderCon 2018, revealing that they are the insignia for Section 31.
The Star Trek: Discovery novel Desperate Hours reveals that the uniform design used concurrently with this variation of Starfleet uniform was exclusive only to those serving on board Constitution-class starships.
