I think fully covered body should be without checks (no matter how smart you are, you won't see black drow skin through the armor/full helmet), but if it's spells and kits, there should be checks. And I think there are RAW?
Not sure on that exactly but I was thinking more like body language and possibly accent. An observant person would be able to pick up on someone not seeming quite right and ask them to remove the helmet.
