Two items come with this set, both for costumes depicting parts of the 1979 movie Alien. Both pieces were worn once for Halloween 2022. The first is the facehugger stage of the Xenomorph. This is made of faux leather. It connects behind the head with five pegs, but two of the pegs have come disconnected. It can still be worn but isn’t as secure as it would be if fixed. This is sized for an adult, not a child. The second is the chestburster stage of the xenomorph. My dog wore this as his Halloween costume by poking it through a hole in a singlet (see photo). I’m happy to send the buyer the singlet as well, but will assume it’s not wanted unless I hear otherwise. The chestburster is intended for humans and has some weight to it so wouldn’t work for a cat or small dog. There’s also a astronaut costume for dogs available in my closet that we used together with these. It’s listed as a rose 🌹 item which means it would be free when bundled together with this set.
