2019 Update: We've added new costumes

Everyone wants to be a part of the coolest group in school. You know the one we're talking about. That group of girls who rule the hallways, have the best hair and makeup, and the coolest clothes. They're the girls who create trends like wearing pink on Mondays and not wearing sweatpants to school. In this case, they're the plastics, aka the Mean Girls: Gretchen, Regina and Karen. And everyone follows their trends for Halloween. Their iconic group Halloween costume: turning the cute and mundane into sexy and fascinating, with lingerie and costume accessories. But don't fret, you can create your own Mean Girls costume, too.

The Bunny

The Queen Bee…. Or, bunny, is the costume of choice for the leader of the group. A Regina costume takes the traditional Playboy Bunny look and brings both natural elements and the color pink into her attire. You'll easily pull off this Regina George bunny outfit for a big bash. And don't leave the confidence at home, you'll need that to be Regina George and rule not only the school but the party, too.

The Mouse... duh!

"What are you? I'm a mouse, duh!" Rounding out the trio with Karen's sexy mouse is a MUST have costume. Our exclusive Karen Smith Mouse Costume is the simple option for those who don't have the smarts like Karen. Okay, kidding! It's easy for the smart ones, too. What's harder will be perfecting Karen's ditzy personality in a way that only Amanda Seyfried can do! Even if no one "gets" your Karen Mean Girls costume, that's kind of the point!
