I'll give a vote for the Bajoran Major, or Jadzia Dax, or even . . . is it Hoshi? The translator on Enterprise?
I'm not much for the spandex "look-at-these-boobs" bodysuits. I mean, c'mon, what sort of uniform looks like that in the real world? I mean, I guess I can't object too much, but why couldn't they just give 7 a shirt and some pants. Maybe a belt. Who knows, possibly even some buttons. God help me if I live until the 24th century only to discover people are using velcro and zippers instead of good-ol' stylish buttons.
