Halloween // I need advice figuring out a costume

I (20,f) am having a really hard time choosing a costume, for reference, I'm petite 5'0" and I have long brown hair. I love movies so I wanted my costume to be movie-themed like Mia from pulp fiction, Bella from twilight, or Maxine from X. I wanted to do Patrick Bateman but someone already picked that, wigs do not suit me so I would rather stay away from them. if anyone can give me any ideas for a costume that would be awesome!!!
