Okay so, I personally have put outfits on characters I don't enjoy and they can be annoying to attempt getting a 2nd time for a character you may like a lot. This can also be harder to do because you may have to wait for a new gacha or sales event to come around. So why not create an NX item that you could use to box up your outfit into an airtight version? Seeing as this would most likely be used on premium outfits it could go for about 30k-40K NX? Just something I thought of and would personally invest in to move around outfits I enjoy and there wouldn't be a major loss of money for Nexon either.
