Hi guys, I've just started on my first real mod and was wondering if something is possible, if so how to do it?

What I would like to do is have an armor equipped on the body at all times except when other body armor/clothes are worn.

e.g: Have Iron armor equipped until I equip steel or clothes but when I take the steel off I am once again wearing iron.

Would it be better to replace the "naked body"?

looking forward to hearing your thoughts and ideas.

Thanks
