Katy Perry
From her whipped cream bras to her bright blue hair, this sassy songtress has been a Halloween favorite since she first kissed a girl (and liked it). There are plenty of ways to sport Miss K.P.'s style and you can even buy a costume inspired by the singer in stores. Unfortunately, John Mayer's phone number is sold seperately (we already checked).
Snooki
Our favorite guidette is brand new mama, but she's still not afraid to rock her signature Jersery Shore style. Platform heels, anything leopard and a perfect pouf are a must if you're trying to dress like Snooks. Baby Lorenzo, of course, is an optional accessory.
Lady Gaga
Lady Gaga's meat dress? So last Halloween. This year it's all about the comfy balloon costume (and it's a lot less smelly!). Perhaps a similar style is sold at a Sumo wrestling store?
Dr. Dre
Black thermal? Check. Jeans? Check. Beats headphones? Check. Costume complete. How easy was that?!
Miley Cyrus
We have mad love for our Miley bird but she was asking for Halloween copycats when she chopped off her locks. A Draco Malfoy wig and any kind of crop top should do the trick. Five dogs and a hot Austrailian fiance are optional.
Christina Aguilera
Her "Genie in a Bottle" days might be over, but Xtina still makes one fab Halloween costume. You must rock colored hair and killer curves if you're goal is to dress like the "Your Body" singer. And don't forget to bring out an extra dose of diva 'tude!
