During the events of the Alderaan civil war of Star Wars: The Old Republic, House Alde nobility wore this blue, gray, and orange suit with long capes. Some wore gloves, while others did not. Some also featured angled shoulder fins.
This costume was worn by nameless NPCs in House Alde, including curators, delegates, librarians, negotiators, nobles, and officials. Excellent 3D turn-arounds of this costume can be found on Jedipedia.
