I'm on board for the outfit exchange token. For someone like me who has all of the outfits that the stage 10 box has, the box loses a little luster. A few options off the top of my head:
-Old event outfits
-outfits that were time sensitive that new players would never had a chance to get before.
-outfits that were part of old rng outfit boxes (ones that require designer threads).
-Or just a stack of designer threads big enough to afford one of those outfits.
