So, a little bit of insight from Orlando's side of things.
I asked someone I know what they thought about the costume and what the situation is, their response was they have no idea as they're not the one's handling that, it was its own separate thing from HHN. So if it didn't come from HHN, it probably came from Blumhouse and there goes any excitement I had for the film as that design is most likely accurate to the film.
Respectfully, your friend is misinformed.
