dude I would love to have that outfit for myself
And I would so love for you to have an outfit like that.

Speaking for myself, I don't see any real difference between the look of Voyager and TNG. So they used warmer colors on the TNG set and more metalic ones on the Voyager one, so what?Most of the Voyager sets were built from the Ent-D ones, i.e. Sickbay, corridors, transporter room. A new coat of paint keeps them from being dated?!?!?!?
How does the Enterprise-D look like a luxery liner? I've been on cruises and they don't look anything like the Ent-D on the inside or the outside.
And I don't get how the TNG sets look 80s. I was a kid in the 80s and the one thing about them, artistically, was loud primary colors. Look at the Police synchronicity tourh, Cyndi Lauper videos, etc. It was all about loud clothes and colored hair, basically, post-modern art to an extreme.
The TNG sets imo, don't echo the 80s at all. The only thing that looks dated in TNG, imo, are some of the earlier (seasons 1 and 2) imo.
The inclusion of the ship's shrink, according to Ron Moore and Joe Menkosky, was something that makes TNG look dated, because therapy took off in the 80s, but as for the rest, I just don't see it.
The original show looks dated with its more primitive interfaces and some of the pulpier conventions (it did a great job of keeping what was great of the past with westerns and old adventure movies and looking towards the future imo), but, honestly, I don't see any big differences between TNG and VOY at all. IMO VOY was just TNG v2.
You must not have seen a whole lot of 80s style architecture. Everything was earthy, bland and bright.
But I didn't just mean the look of the ship. The characters and stories all had 1980s conceptual undertones.
Much of the dialog is time-stamped as well.
