Posted this last night but saw a couple people still asking about fashion unlocks.
Assuming this works the same as SWSH then we need someone with all clothing unlocked, including pre-order items to load up their save in PKHeX and export the block:
*Array KFashionUnlock
Upload it here or wherever and we should be able to import the block to our saves and have all the fashion. That's how it worked in SWSH so hopefully works the same here.
So please, anyone with all the exclusive/preorder items either share that block or share your save and hopefully we can get a full fashion unlock.
