Why Troi Didn’t Wear A Star Trek Uniform Until Later In TNG

For most of the run of Star Trek: The Next Generation, Counselor Deanna Troi (Marina Sirtis) didn’t wear a traditional Starfleet uniform. Despite being one of the main characters who spent much of her time on the bridge of the USS Enterprise, Troi wore various civilian outfits throughout the first several seasons of TNG. It was not until the last couple of seasons, when Troi began taking on more responsibilities on the ship, that she regularly began wearing a Starfleet uniform. TNG never offered an official in-universe reason for why Troi wore civilian clothes for much of the show’s run.
