Currently this item is going to get fixed in the future - at least that is the line Zenimax are holding firm on. At the moment, Body Marking alterations from your DEFAULT selection (at character creation) will be reverted to on relog, or often after a load screen. This means you would have to change your body marking to the desired selection every time you do this.
I would suggest holding off on purchasing this item until it is fixed (if you were planning on doing so). I spent crowns that they won't refund, and I would hate to see anyone else have the same problem
I hope this helps anyone about to make this decision...
I should add, this isn't the case for everyone, but I think it most affects anyone who has other parlor effects/costumes active at the time.
