I remember while playing a Jedi Consular in Beta that there were two awesome looking robes. not the skirts that most of us have to wear, but proper robes. Open, flowing and hooded. I think they both came from Coruscant, one was blue-grey and the other was brown.
Anyway to my point, I assumed, playing an Inquisitor (the mirror class of Jedi Consular) that there would be some awesome black/red/whatever Sith equivalent to these robes. Sadly I've not found any as of yet.
Please Bioware, consider re-colouring the model and putting some out there for Sith side. I don't mind wearing a skirt if I have to, but an actual robe to go over the top of it would really look the part!
Edit: Not sure where I got Guardian from, I was in fact referring to the Jedi Consular I played!
