This costume was worn by the Trill Scientist 'Bejal Otner' (Tim Ryan) in the Star Trek: Deep Space Nine episode Rejoined in which his older sister 'Lenara Kahn' (Susanna Thompson) rejoined with 'Jadzia Dax' (Terry Farrell) in a taboo Trill relationship. The tunic is crimson and black stripes with crimson and gold patterned shoulders and sleeves. The neckline is crimson as is the ribbon trim. There are two slits up each side. The accompanying pants are crimson and black striped. Costume comes complete with costume tag.
Images from the original auction listing are included as well as a couple of screen-caps from the ST:DS9 episode Rejoined.
UPDATE: It would appear this costume was reused in the DS9 Season 6 episode Behind The Lines by an alien character that passes Major Kira and Rom in a hallway (added a photo).
