How Many Costume Changes?

I read somewhere that the most costume changes in TOS was four. Supposedly France Nuyen, Elaan of Troyius, had the most costume changes than any other female guest star. Well, I'm here to dispute that claim. You can double check me on this (and I'm sure you will) but the character who had the most costume changes was Lenore Karidian (Barbara Anderson) in The Conscience of the King. She wore a whopping six different costumes in this one episode. Here's proof.
