To boldly dress as no one has dressed before… In another universe, that could have been the "Star Trek" mission statement. Sure, the veteran franchise has spent much of its 60-year lifetime seeking out new life and new civilisations, but it's also been preoccupied with keeping crews fashionable as they explore the final frontier. It seems that nobody wants to make first contact sporting last year's jumpsuit. The sheer volume of uniforms worn on Federation duty is mind-boggling, as Starfleet has turned regular style updates into one of its prime directives. So, as "Trek" celebrates its 60th anniversary, we take a warp-speed tour through the outfits Kirk, Picard, Sisko, Janeway, and the rest have hung in their wardrobes.

As such, the uniforms worn by Kirk and co were rather more casual than standard forces' issue. By the time the Enterprise started its five-year mission in earnest, the outfits had been through a couple of subtly different evolutionary stages (in pilot episodes "The Cage" and "Where No Man Has Gone Before") before costume designer William Ware Theiss zeroed in on those now-iconic designs.

The command sweaters worn by Kirk, Sulu, and Chekov were actually green in real life, but a combination of studio lights, early color TV tech, and the velour fabric made them appear gold on screen.

The loose-fitting, pajama-like uniforms came in an exciting range of light blue and beige (newly promoted Admiral Kirk had his own special design), with departments denoted by a flash of color behind the Starfleet delta logo. Uniforms came with a built-in fanny pack (a medical monitor, apparently), while engineering and security were given protective clothing. The crew also got jackets to wear on chilly away missions.The other Original Series moviesThe iconic maroon Starfleet uniforms that debuted in "Star Trek II: The Wrath of Khan".

"When I watched the TV show, I never understood why they were all running around in pajamas," he said, "so I tried to change some stuff". The one thing that did remain from the Original Series was the voluminous cut of the pants, albeit enhanced by a natty red stripe down the side. Otherwise, this was a complete overhaul, as Fletcher introduced maroon tunics — arguably more flattering to the ageing crew's waistlines — over color-coded turtlenecks. The tunic was secured via a matching epaulette that also carried rank-specific insignia.
