OMG, KAREN...

You can't just ask someone why they're a mouse!  Well, that might be what the other Plastics think, but we think that Karen should be able to ask anything that she likes.  When you're the only nice one in a group of mean girls, there are a lot of things that you should be forgiven for!  Sure, the gal might seem a little ditzy, but that's only because she's so focused on developing her extra fifth sense for predicting the weather.  These are tough skills, folks!

Plus, who of the rest of the Plastic crowd are so capable of blending into any scenario?  With that delightfully open mind (admittedly partly because it is just a little empty), Karen is not only willing to accept all sorts of different people but can become so many things, too!  How many psychic, weather-forecasting, rich, highschooler mice-girls can there be out there!?  Karen Smith is clearly one in a million.  

DESIGN & DETAILS

Our team of designers faced all the fugly troubles of the high school cliques in order to put together this perfect (and officially licensed) Mean Girls costume featuring everyone's favorite Karen Smith's "I'm a Mouse!" costume!  (How meta is that!?)  This exclusive look includes a black one-piece bodysuit covered by a super-short, thin-strap chiffon baby doll dress with a shiny ribbon belt.  The mouse ear headband is wrapped in gray fur with pink satin for the inner ear.  Folks might think you're just a mouse, but when you quote Karen by saying, "I'm a mouse, duh," all will immediately recognize you for the best of the Plastics!

FIVE(?) COSTUMES IN ONE!

Become a little bit of everything in one look!  Be one part mouse, one part Mean Girl, one part weather reporter, a dose of psychic ditz, and total adorable package when you gear up with this exclusive Mousey Karen look from Mean Girls.
