The real crime here is that price. I'm not even a "make your own costume!" person but you can could pull this off (better) for less than $20.

You'd still be wearing a ****** costume, but at least you didn't pay $100 plus shipping.
Fake edit: At least they responded in a semi appropriate way? It's a step down from removing it but if they keep their word at least it's something.
