This is not really needed, since some of these costumes are for the holidays. Btw VIPs can respawn their costumes with sniper scope, you just gotta use all the costumes you want and after respawning you gotta use the sniper scope once and they will be spawned to. As for non-VIPs, they can use /camera. It's possible, that sometimes this could bug and you won't be able to spawn the costumes even after typing the commands, you just gotta relog.
