Helmets that don't change whatever miraluka mask I chose when I equip them
Pure, plain white (or black) jedi style robes (no extras, no giant shoulder pads, etc.)
Something like the gamorrean axe for shadows/assassins, since we can't use electrostaves and still be viable
Some of the outfits that the Voss civilians and mystics wear
Trench coats without the giant collar on the one currently in the cartel market (Emergency Responder's Overcoat)
