[Suggestion] Added Wardrobe Option
An alternate suggestion to this idea: Customized Outfits.
By this I mean you could buy Custom Outfit Slots from the gemstore, say up to a maximum of 3/4 slots. These outfit slots could then be set to look like your current armour skins. To set each outfit you use a consumable item that uses the armour pieces you have equipped at the time. This will then lock in the outfit to have your current armour appearance.
You could buy the initial Custom Outfit Slots (max of 3-4), then buy Custom Outfit Designer consumable items from the store, which will reset one of your outfits and create a new one based on your armour.
Not sure if this is doable, but I feel it would be easier to use (simply select the custom outfit you want, instead of each piece) and would provide another avenue of revenue for the game.
