DF: Armor Layering and Enchantments

[Stix4armz]

In Dungeon Fantasy I know that you can boost your DR by layering armor, wearing cloth armor underneath mail or plate for example, and I know you can boost the DR of your armor with the Fortify enchantment. My question is if you can layer armor and then enchant both layers of armor with the Fortify enchantment separately in order to gain a further DR boost?

Let me clarify what I am not asking, I know that the Fortify enchantment found in DF 1 is for the whole set of armor and you can't just pay that $100 for Fortify 1 for each piece of armor and crank your DR up that way. I'm also not asking about piece by piece armor enchanting either, though that might be a discussion worth having in another thread. I am just looking for clarity on whether layered armor is considered separate when it comes to enchantments.

If you're layering a full set of cloth armor underneath a full set of plate armor, they are separate sets of armor right? So can I enchant the cloth armor with Fortify and the plate armor with Fortify?

If the answer is no you can't Fortify both sets of armor separately, then my next question would be: Do I get the +1 (or whatever level) bonus if I get caught without my plate armor on for whatever reason?
