How to make a simple armor or outfit replacer?

[ladyvoldything]

I can't find a tutorial for the seemingly simplest thing- how to replace a vanilla model (clothes or armor) with the model from a mod.

 

For instance, say I wanted to replace the hideous shiny vanilla noble clothing with something from Kirkwall Exports or Viva la Orlais. Or replace the "Battledress of the Provocateur" with an armor from one of the Witcher port mods.

 

How would I do that? I know it's a fairly straightforward process in Skyrim but this ain't Bethesda, I'm playing with the big boys now.

 

Help?
