Is there a concept for appearance changing armor?

Like in final fantasy you can get new armor, but it doesn't show up on your character, but does in games like diablo.

I looked it up in the concept fields of some famous RPGs that have it and couldn't find it. It probably hasn't been added or added under a weird name.

I tried searching for it under every name I could think of. Nothing. Should probably be in there. Should probably call it 'Visible Equipment Changes' or something simple. I am usually not a fan of weird names for stuff as I think it kind of defeats the purpose of having an easily searchable wiki if you can't easily search the wiki.

Personally, I would go for the opposite idea as a concept page, ie. non-appearance changing armor.
