I think it would be cool if we could customize our character's "accessories" and actually put it on them. Like the game Murder Mystery 2.
It looks pretty neat and alot better.

Please don't mention any of those HORRIBLE "murder" games.
May sound like a good idea if ROBLOX decides to overhaul the way hats work, breaking every other hat in the process.
