The Costume Savant

Karen Smith probably won't be winning any awards for kindness... or smarts for that matter. She's often the most clueless member of the Plastics, but you have to admit that she has an amazing style sense, especially when it comes to choosing a costume! In fact, she may just be a complete savant when it comes to creating costumes. She learned one of the natural rules that it took us years to figure out. Costumes don't need to be complicated! Sometimes, all you need is a cute outfit and a pair of mouse ears to create the perfect look.

Now, you can harness Karen Smith's brilliant style with this officially licensed costume from Mean Girls! It's a cute and easy way to cosplay as your favorite character from the movie.

Fun Details

This I'm a Mouse, Duh! Costume is an exclusive outfit designed by our expert costume designers. They created a look that mimics her signature costume from the movie! It begins with a step-in bodysuit that has length-adjustable straps that fit around the shoulders. The babydoll dress features a ruffle top with an elastic edge. The included satin ribbon ties around your waist. Of course, the most important part about this outfit has to be the mouse ears... it's what lets everyone know that you're a mouse, duh! The mouse ears are attached to a faux fur headband that fits on your head to complete the look. Once you have it all on, everyone will know that you're a cute mouse!

The Plastics are Back

    not the best quality. for the price I paid, I expected a bit more.

    the dress is pretty short but thats not too much of an issue. the silver sash is way too short to tie properly which annoys me, because without the sash, the dress is super poofy and not as flattering. overall im not upset I bought it.
    Bottom Line: No, I would not recommend this to a friend.
