With only a week to go until Halloween, you're likely on the hunt for a costume that's easy, fun, and original. In addition to some hilariously punny celebrity name costumes [1], we've also got another slightly obscure pop culture look that is sure to impress your friends while also eliciting a few blank stares: Regina George in sheep's clothing.

Remember back in September when Taylor Swift told Rolling Stone [2] that her new song "Bad Blood" is about another female pop star? The rumor mill went into overdrive, with most Internet sleuths concluding that Katy Perry [3] was the unnamed singer Taylor was talking about. Days later, Katy sent out a cryptic tweet:

Watch out for the Regina George in sheep's clothing...

— KATY PERRY (@katyperry) September 9, 2014 [4]

Which brings us to your hilarious Halloween costume; all you need is a long blond wig, pink miniskirt and cardigan, and pair of sheep's ears on a headband (you can also make a tail out of cotton balls). Print out Katy Perry's tweet, glue it to a piece of cardboard, and wear it around your neck. Add a Burn Book, and voilà! You now have the most original pop culture costume at the party.
