I work on station and currently male and female sailors wear the same uniforms (the pants have a slightly different cut). Their Dress Whites and Dress Blues are the same old ■■■■■■■ jack tops. On occasion I’ll see a female wearing a uniform skirt. But not usually if they are in formation, then they all have trousers. And of course the working uniforms are all pants.
DS9 ended in 1999, Voyager in 2001 and the last Trek ended in 2005. 15 years ago.
Social norms have changed significantly since the 90’s, or even 2005.
Last year I was on travel and we hit a restaurant near a university and young crowed was all decked out in 70’s mini skirts, sandals and flip flop rather than the boots and platform shoes I remember. I think they call it retro or something now.
Anyway, the point is, fashion cycles and each new group/generation thinks they are the cutting edge. What people where in any given year is just background garnishing.
