Jacket or jumpsuit?
Is there any rhyme or reason to why characters randomly switch between the full jumpsuit and a jacket and pants, like in the later seasons of DS9 with the outer-grey uniforms with colored undershirts? I'm trying to procure a uniform of that style and I don't know which is more common. Is it just a choice for Starfleet members?
Example. Kira is just wearing the jacket here, even though it looks like a jumpsuit otherwise.
