I agree with everyone stating the wardrobe should still show the type of weapon and armor you are wearing, to give an idea to everyone looking at you, about what your strengths and weaknesses are most likely to be (you could still set up your stats and skills in a way that would surprise them, though). The argument referring to knights wearing robes over chain mail/coat of plates, doesn't really stand. Trust me, your first glance will tell you whether he's got armor underneath. The cloth was there to keep the dust away, and show the crest. As far as having good gear that looks poor, for deceptive purposes, That would indeed be interesting, but only if there is a reputation mechanic with a powerful in game impact (access to certain areas in towns, guard patrols will only protect noble people and so forth, npc-s refuse to talk to or serve plebs and vice versa, of course) that derives from how rich you look.
