Right now this is purely a technical limitation of the system. The "current" wardrobe uses the filename to determine what layer the item is on, so in the event of changing a bunch of items to a new layer they have to changed as files as well, which is messy and not something or are well equipped for on our end.

The new wardrobe(s) instead use a field in the database that makes it easy to change what layer they are on, so hopefully we're heading in that direction soon and it'll be easier for us to make these kind of changes across the board.

doesn't make these choices anymore :)
