Scouts, Preists, and Fighters only get three Gis.
Tunic of Echoes from COA, Dustdevil Jerkin and Gi of the Jarsath Swifttail from Maidens are all you get, and hopefully ever will get.
I wish that the developers would give us back our individuality by making all three items Monk/Bruiser only, and then adding in an NPC who will trade a new chest item with the exact same stats but a different, non-gi appearance to everyone else.
Furthermore, what they need to do is develop a unique one-item-full-body appearance for all classes. It's just inappropriate for other classes to show so much skin when the brawlers have already cemented that it's thier look. We can afford to look half-naked because the more stuff we wear, the harder it is to move and dodge. It's not our fault that the developers chose to give us the full appearance with just one item. Even casters still show thier gloves and boots underneat the robe.
