I like Seven of Nines's cat suits, but you must have a brilliant figure to wear it. I also liked the clothes Janeway had on in Concerning Flights when she visited the planet.
I just had a horrible daydream of Scotty or Pulaski in one of those catsuits!
My favorite has been the uniforms from First Contact/late DS9.
And there's no topping the miniskirts from TOS.
