You know what bothers me? The fact that in the original Harry Potter movies wizards wear "stereotypical" wizard fashion (robes, hats, etc.), but in Fantastic Beasts they wear (mostly) what any regular 1920's person would wear. Doesn't that get you? It's such a tiny detail but it takes away from the illusion of the world. I've tried to come up with some "explanation", but idk what to say.
This gets super in depth, so pardon my geekiness and keep reading if you’re interested in my wizard fashion breakdown :)
