Season 4 Aurelia Costume, from episode "Soon the Nearing Vortex" played by actress Sonya Salamaa... There's production writing inside the garment but its hard to read which is why I was thinking it was one of Trance Gemini's costume pieces, that and it has a HighGuard logo on the front, wither way this is a gorgeous screen won item and is in very good screen worn condition...
