Indeed, I think there's room for all kinds of fun little things to try out for a different appeal though, take this for example.
The hood has a certain aesthetic that works with a heavy coat but a mple mask tucked into a collar can create a totally different perhaps even more nister vibe. Now you're not dealing with a costumed killer which could be as unintentionally amung or off putting as a spandex superhero, but a psychopath that mply doesn't want you to see his face. If someone came after you, decked out in a full scarecrow costume even carrying a ckle, they'd probably have to cut someone down in front of you to realize they mean buness. If you saw someone in a suit, dressed to the nines, carrying a knife with a ramshackle mask coming after you in a hallway, you'd definitely be in oh shit fight or flight mode from the git go where if it were a scarecrow you'd probably be like hey man great costume. Not to spam you with a wall of text but I love getting into the mindset of these kinds of characters and trying to see how the outde would view them as well. For me, every day really would be Halloween to keep everyone on their toes.
