I purchased the Crown Crafting Motif: Pact Style from the Crown Store. When I chose to "dress" my character in the Pact Style Motif, (armor and weapons), I had to pay GOLD to make the change at an Outfit Station. Not a big deal however, I just noticed that after paying gold to change from a Sword to an Axe, I have to pay gold AGAIN if I want to change back to a Sword! I thought / figured that since I already paid gold for the Sword, I wouldn't 'need to pay gold again to change back from the Axe to the Sword.
I"m guessing that any time you make a change at the Outfit Station, no matter the case, it's going to cost you gold. BTW, I purchased the Imperial Edition of Elder Scrolls Online and didn't have to pay gold to change my look to Imperial..........
I really think that once you pay gold to make a change, you shouldn't have to pay gold to go back to a previous outfit.......just my two cents.
