Ok, I don’t know if already exist something like that and I am too blind to note it, but the suggestion is: why there is a PvP wardrobe and not a PvE skin one?
If I would change my skin with another “old” skin I have to craft or buy the armor piece I need and apply the skin on my new armor, so that everyone (or the highest player percentage) use alwyas the last skin they find.
I think that would be awesome if with a transmutation stone we could destroy the armor or weapon pieces to add its skin in a Wardrobe. When we will want change skin, we will have to open the wardrobe skin and choose the “new” one.
