Halloween // costume ideas for long dark hair

i have very long dark hair and typically try to base my costumes around my hair. f25 and i don’t mind doing gender bend looks but love the idea of a more adult (nsfw) costume.

some costumes i’ve done in the past: jennifer check (jennifer’s body) ozzy osbourne cow fairy playboy bunny clown and lots of other characters when i had other hair colors

im a big fan of gory costumes, have a little experience in sfx make up, and treat halloween like prom. it’s a big event for me and i don’t mind putting a lot of time, money and energy into it. any suggestions would be great!
