I don’ t know exactly what this costume is. Must be from some video game or anime… something like that. Still cool anyway though. Can anyone give me a clue in the comments?

This is a great costume if you’re a nerd. In that case you will know how to rig up lights to the eyes and everything. Plus, your friends will get the joke. If you end up at a party of religious people get ready to explain what the heck your costume is every 5 minutes. Overall, well done though.
Creative, but lazy. This is one of those costumes that was funny the first time. If you’re the first or only person you know to wear this you can pull it off.
