Halloween // Costume I want does not seem to exist

This costume is only listed at one store, has no reviews, and has not been available for at least 3 years (since the first time I found it). Logic would suggest that it does not exist. But since it has a picture, I am hopeful that it (or something like it, at least) exists somewhere, somewhere on this precious Earth. I've done plenty of digging, to no avail, but I was wondering if someone else might have better luck finding it or its closest lookalike.
