When Burnett and Lay work on the season 6 VAM, I hope they tell the story of Troi's costume change. There has to be at least one interesting anecdote there.
If RDM records a commentary for Chain of Command, then that should do the trick.
Chain of Command changed not only Troi's costume, but also got rid of Livingston (the fish in the ready room).
We will get a 30 minute documentary about why Troi was put in the uniform in the S6 BRs.
It was Moore's idea by the way and Marina happily went along with it.
