I've got Halloween 2018 all locked up. I'll be dressing up as Kylo Ren - fifteen years after the events of The Last Jedi. In this headcanon, Schweitzo Ren becomes depressed at all of his terrible behaviors and goes on an extended eating binge. Rey catches up with him and immediately asks that he put on a shirt, but for an entirely different reason.
I've already got the nose and the hair, but I have to work on that pouty lip thing that Adam Driver's got going on there.
