I just watched DS9 EP11 (homefront) and EP12 (paradise lost).
I was under the impression that Starfleet uniforms changed over time. We see the uniforms change several times, in the movies I believe. When new uniforms are created we see the new ones being implemented and old ones slowly phased out.
On DS9, they wear the Color designation on the shoulders with the greyish blue turtlenecks.
But in the episodes I mentioned, when Sisko returns to Earth, they change back into TNG era uniforms.
Why do they change back to these uniforms?
Are there different uniforms for different area's of service? I thought the only difference in uniforms was color designation. I know that with so many personnel in StarFleet they can't get everyone into new uniforms right away it takes time to phase them in, but I would think StarFleet Command would have had the new uniforms by this time!
I even gave thought to maybe Ship uniforms differ from Station uniforms, but DS9 and Voyager are the same. And TNG and the ones in these episodes on Earth are the same.
So, what is the significance of wearing different styles of uniforms?
*I posted this in DS9 forums since I watched it in DS9. Sorry if this should go somewhere else.
I think it is meant to represent the nature of the posting. Both uniform styles existed at the same time in the Trek universe, with TNG maintaining the torso colors while DS9 had the shoulder colors. I've heard that the torso colors were more formal, more of a sense of representing the Federation on a larger scale, while the should colors suggested less formal posting. You should note that Voyager used shoulder colors as well, and its mission was not as diplomatic as Enterprise's.
Why they suddenly became the norm for Voyager and Generations, though...
I don't know about you, but the TNG uniformed looked a lot like sweatpants to me.
