If I can suggest one article of clothing I would recommend some sort of mage robe, preferably a higher end-looking one (maybe the hoodless archmage's robes, or a retexture of such?) Unarmored characters are frequently mages, so reskinning the archmage robes and making that enchantable or just plain given the archmage enchantment would probably be best. If not that, then the bartender set, since the two argonians in the bee and barb both wear that, and they're two of the few argonians in the game. The bartender set has a retexture of it, so you'd get two outfits with one stone, and you can modify the very few argonians who don't wear the bartender set to wear that. IIRC some of the dock argonians also wear that outfit. And, of course, modifying that particular outfit to fit a flatchested digitigrade female argonian would be grand~
