Sure they were the 60s, 70s, and 80s equivilants is all.
Uhura and Rand didnt do much each week but show some leg and bring the captain his coffee.
And i trad in the making of trek where would costume guest ladies in as little as could get away with by the decency rules of the time.
By the time BSG and Buck Rogers came around women's parts had started to get more substantive roles but for the most part they were on the brige looking cute or in wilmas case posing with a gun looking cute.
There characters were just a little more developed.
And even tho 7/9 was intended to just be T&A she wound up being one of the best actors/characters on the show.
Where there outfits may seem tame to us in the 00s to the audiences of the day they were just as scandalous.
Go go boots and mini skirts for TOS trek
Skin tight flight suits for buck rogers and BSG and low cut body suits for Troi
Women characters are usualy put in as form fiting an outfit as possible to acentuate there boobs and curves.
Ryan and Blalok just happen to have more boob to accentuate
