What to wear as Mia Allen: A red floral dress under a grey sweatshirt that says Michigan State on it, or ditch the sweatshirt and wear a long-sleeved red dress (you'll want to be covered in fake blood anyway). Rock black lace-up boots, and bring around a fake chainsaw, too.
How to act as Mia Allen: You're a recovering heroin addict who's trying to quit cold turkey, so you're going to be a bit on edge. Don't go near any basements or wander into the woods by yourself.
