cosmetic items - try before you buy
I think before you buy any cosmetic item for a character you should be able to try it without using any form of currency to buy it ( gems , gold auric cells ) for at least 6 hours to see if your sure you would like it or not . the timer can either decrease with current use or once the trial period is started it can reduce to zero even if it's not being used , depending on what BHVR decide , and the more expensive items can give you an extra 2 hours .

I would rather they make a little box area (kinda like the tutorial) with basic things (vaults, still survivor, killer who is swinging) in which you can test a cosmetic.
