People want to be able to replace some items that take up two slots, like hooded robes or the stovepipe armor, with the appearance of gear that takes up only one slot, but have appearance slots for both of those slots. Otherwise, the result is that you appear to have no head gear equipped and can't have any appearance in that slot.
