Sister Halloween Costumes: Katniss and Prim Everdeen From "The Hunger Games"
What to wear: For Katniss, you need a brown jacket, brown pants, and a dark shirt; the long side-braid is key. For Prim, go with a tan skirt, a white blouse, and two braids.
How to act: If you're Katniss, volunteer for everything. If you're Prim, ask people if they've seen Buttercup.
