A, thanks, that's what I needed to hear.
So let me get this straight: It has the same name and drops, at least in part, by the same bosses, but it is a different item, depending who kills that boss, and when you mail from an imp to a rep character it remains the imp item?
Fortunately this is for a chiss Jedi Knight. I suppose her mom could help her with her wardrobe without the Empire finding out. Must be worth something being a free agent.
The item switches appearances depending on the character's faction its currently being held by. So unfortunately if you give it to a pub character it will turn into a long brown robe.
