I did a quick forum search and found nothing.
I think it would be great if ANet implemented a Wardrobe in the same vein as the sPvP wardrobe.
This would have a 2-fold benefit.
1)Min-Maxers would want to fill their wardrobe with every style, it would add an element of game-play that would make more people want to do dungeons and explore crafting.
2) Those that want to swap styles often. When you transmute it destroys your previous item, I have used multiple transmute stones just to keep styles I might want in future, this fills the bank and gets frustrating as I need new gear every time I want to change style.
As the sPvP wardrobe requires you to add the stats you want, this could work like the Hall of Monuments gear, when you take it out of the wardrobe (while leaving it available) you can transmute for free. Or have a cost, but have it act the same way. I would rather pay silver for the style that I already have and not destroy another.
