I know fuck all about Harry Potter tbh, but I don't wanna go in some basic schoolboy fit to be one of the kids. Any fun characters/creatures/concepts I could go as?

I love goin hard at parties tho so it can't be anything imma get too hot in.

Serious and non serious answers welcome.

EDIT: I decided with my other friends that on account of our mullets we are going to go as lost hobbits that followed the wrong wizard. A bonus is that the hobbits dress drippy as fuck and smoke a pipe. Feel free to keep riffing though cos these are all hilarious ideas!
