Halloween // Halloween Costumes

F (23) and F (25), best friends who are both brunettes and 5'4 looking for duo costume ideas that aren't Kim possible, Velma and Daphne, sl*tty chicks, etc etc.

I love the idea of Patrick Bateman and gender swapping but we can't both do it, looking for something simple enough to thrift all the clothes but not something where we'll have to explain our costume to everyone. I'm straight and shes bi if that brings any ideas to mind. She loves psych thrillers but hates horror, and I love horror etc. I've played with the idea of Coraline and Wylie but am looking for more ideas, so list them below and give us some ideas. Our friend group went as all of the Akatski last year. Oh, it's for a bar crawl btw. Thanks friends!
