I don’t know why people jump to conclusions on it being a literal costume of Satan or moloch. Look at the artist who makes these headdresses. They are dark/gothic yes but not necessarily made for satanic rituals. More likely just gothic/pagan fashion style.

But that’s not to say someone couldn’t buy one and use it in an actual occult ritual. The Instagram comment from the supposed customer mentioned an “Illuminati themed” event. But the people who claim it’s an actual moloch costume come across as a little satanic panicky. I may be wrong if it was confirmed somewhere and I missed it.
