There's a white robe that drops in Taral V, if I recall my instances correctly. It's one where you basically go to a city similar to Nar Shaddaa. and is low 30's ish.

The OP is a sith.. He can't do Taral V.
Kids on the internet these days are so quick to post but not even read what they are posting to.
