Tell me that's the very first mockup at least. I hope so. Please let that be the case. That can't be a real costume for a major character in a giant big-budget film. Please don't let it be real.

Is he trying to evoke the feel of a college production of a play? This would count as competent costuming in some contexts under certain limitations, of course. Blockbuster movie shot on extremely high def film is a weird one though.
