Crown yourself and your friends with plastic crowns, just like the Plastics from North Shore High!
Rock a big, voluminous hairstyle and share your fierce look on social media.
Host a costume party and let your friends channel their inner Mean Girls characters.
Try out your Halloween costume early, just like Karen Smith would.
Be like Karen Smith and proudly declare, "I'm a mouse. Duh!"
Enjoy a toaster strudel for breakfast, just like Gretchen Wieners' dad invented.
