Corellia’s governing council was a focal-point in the war between the Sith Empire and the Galactic Republic during the events of Star Wars: The Old Republic. The Corellian councilors all wore a fairly standard uniform of a tan tailored suit, with a diagonally-striped red cape, and brown accents. This costume is similar in style as the Generic Old Republic Diplomat, but uses a set color palate. This outfit is worn by Councillors Caicos, Delquis, Haronn, Jalta, Rodin, and Saiak, and is also available as a player character oufit.

Jedipedia has excellent 3D turn-arounds of this NPC outfit under the search term “Councillor.” PC armor references from Swtorista.
