Halloween // Halloween Costume Ideas

Hey! My Husband(24m) and I(22m) are looking for couple costume ideas. His company always has a trunk or treat for the kids so it has to be at least mostly kid friendly. Last year we were our DND characters and everyone loved it! This year we also live in a kid heavy neighborhood so we want to decorate in a way that corresponds with our costume.
So far i'm thinking Vampire and Werewolf (classic style)
Or maybe a Clown and Ring Master?

any and all recommendations are welcome!
