Invisible Cloak

I've always hated cloaks and I want to see the back of my CS. Please create a cloak that does this:
1. Is transmutable to any cloak.
2. When transmuted to a cloak, causes cloak to no longer be visible when wearing it so that I can see the back of my fashion CS.
Pleeeeeeeeeeeeeeease please please please pleeeeease! Any players who love this idea reply!
