Terr Taneel was a senator during the final days of the Republic, and is seen as part of the Welcome Committee when Chancellor Palpatine returns as well as at the Opera and in Bail Organa’s office (cut scene). This outfit is worn at the Opera and at Bail’s office.
The outfit consists of a floor-length, black lace dress with an embroidered, floor-length tabard. On top of that is a heavily textured, thigh-length, black jacket. She wears a wide, textured, black hat that is open in the back. From each side hangs three triangular pendants. Her hair is bright red and in a braided bun.
