What to wear as Laurie Strode: High-waisted flared jeans, a light-blue or denim button-down shirt with a big tear and bloody smear on one shoulder, and a brown feathered wig. Make sure you bring Laurie's trademark accessory out on the town with you, too: a wire hanger.
How to act as Laurie Strode: Just run around screaming or talk about trauma.
