The Ultimate Guide to Rocking a Mean Girls Halloween Costume

The Ultimate Guide to Rocking a Mean Girls Halloween Costume

Listen up, because I’m about to spill all the tea on creating the perfect Mean Girls Halloween costume. As someone who’s been obsessed with this iconic movie since forever, I’m here to help you nail that perfect Plastics look.

The Famous Regina George Bunny Costume

Let’s start with the queen bee herself. Regina’s pink bunny costume is literally Halloween gold. Here’s what you’ll need:

  • Pink strapless bodysuit (the more sparkly, the better)
  • Fluffy white bunny ears
  • White bow tie
  • Fishnet stockings
  • High heels

Pro tip: Don’t forget to practice your Regina attitude. That costume’s nothing without the signature eye roll!

Gretchen Wieners’ Purr-fect Cat Look

Gretchen’s sleek cat costume is totally fetch (yes, I’m still trying to make fetch happen). You’ll need:

Karen Smith’s Mouse-ka-tear Ensemble

Sweet, simple Karen rocks the mouse look like nobody’s business:

  • Gray dress or jumpsuit
  • Mouse ears
  • Tail (optional but recommended)
  • Confused expression (mandatory)

Group Costume Magic

Want to roll with your squad? Here’s how to coordinate:

  • Assign roles based on personality
  • Keep the color scheme consistent
  • Don’t forget your props
  • Practice your slow-mo hallway walk

The Burn Book Bonus

Whether you’re going solo or with friends, carrying a Burn Book takes any costume to the next level. Make your own with:

  • Pink notebook
  • Black marker
  • Magazine cutouts
  • Your best Regina-inspired insults

Where to Shop

I’ve hunted down the best places to find these costumes:

  • HalloweenCostumes.com
  • Party City
  • Amazon
  • Your local thrift store (for DIY versions)

Remember, on Halloween we wear pink! Or bunny ears. Or cat ears. Or mouse ears. You get the picture.

Just don’t forget – these costumes aren’t just about looking the part. It’s about channeling that Mean Girls energy (minus the actual mean girl behavior, cause we’re better than that).

Final Tips:
  • Start shopping early – these costumes sell out fast
  • Do a dress rehearsal
  • Take lots of pictures
  • Own it like you’re walking the North Shore High halls

Now get out there and make fetch happen! And yes, I know that’s not going to happen, but a girl can dream, right?
