Crate Costume

Get a friend to put one on too. The description says it plainly: the costume is for trolling, and it works best in pairs. Picture an online raid on your own base. The two of you stand still in the loot room between the large wood boxes, and the raider who blew the door opens one box after another until one of them turns around holding a shotgun.

Apart from the description, its row matches A Barrel Costume: no recipe, no workbench, no durability. You cannot craft it, and it most likely comes from Halloween loot. It will not stop a single bullet.

A costume you can actually sew yourself is the egg suit. The rest sit under Attire.
