The only one I know is dressing up for sure is my college freshman - LOL - as some manga character. DS1 (16) hasn't dressed up since 8th grade so unless a party crops up that requires costumes I think he probably won't. DS2 (14) might dress up, he did not ToT last year for the first time but I don't know for sure if it's really over or if that was pandemic induced. My other two trick or treated for the last year in 8th grade, so I guess DS2 might if his friends go.
