The only thing I see in this thread is whining, if you are willing to collect every costume in the game, including cash shop ones which would cost you quite a penny, then you are insane if you can't accept that this is something that is not needed to enjoy the game. If you want to spend tons of $ to buy costumes, shell out a bit more for a premium.
If you are one of the people complaining about faction outfits then you are silly as well. The only faction outfits you should really care about are the crimson and cerulean ones, which you only need one of. This is not to say if you're interested in the other factions go for it. But the amount of costumes that are faction specific is not enough to warrant free wardrobe.
If you want wardrobe pay for it, if you don't want it just get better at managing your inventory, it's not that hard.
