I walked into the Silver-Blood Inn the other day, only to find Vorstag wearing all Glass Armor excluding the helmet.

Did you hire him as a follower one time? You probably gave him armor, in that case. He might have also grabbed them off the ground, and equipped them, although armor tends to be kept in inventory until they're hired again.
It could also be a mod; check them to see if they give NPCs better armor or something.
