Prince William. You and your sweetie can pretend to be royalty for a day as the year's most famous newlyweds (sorry, Kim and Kris, but we're talking internationally here) by dressing up as Prince William and Kate Middleton on their wedding day in an Irish-Guard uniform and bridal gown. Billion-dollar bank account not included.
Kate Middleton. While this dress was not designed by Alexander McQueen as the Duchess of Cambridge's was, it's not a bad Halloween knockoff for $39.99!
Kim Kardashian, Reality. Kim Kardashian has barely gotten any publicity this year, so give her a little extra by dressing as the reality star this Halloween. Sure, the dress, wig, and heels are integral parts of the costume, but if you really want to look like the new Mrs. Kris Humphries, well, you know where to stuff it
Pauly D, Reality. Got a third wheel cramping your couple's costume style? How about making him go as DJ Pauly D? In addition to the bouffant-style wig and the tank top that comes attached to flesh-colored "arm" sleeves with tattoos, grab a pair of headphones to complete the ghastly Guido look. Self-tanning cream optional.
Snooki, Reality. Pint-size gals can dress up as The Situation's former fling and "Jersey Shore" housemate Snooki with this leopard-print dress, giant wig, and tons of makeup. Just make sure you don't end up getting punched in the face at a bar!
The Situation, Reality. Put a little Jersey into your costume by going as someone whose 15 minutes should have run out last Halloween -- Mike "The Situation" Sorrentino. Go ahead and add the gelled hair and gold chains, but keep in mind that the outfit's big draw is the "Jersey Shore" star's chiseled abs. Though you probably won't fool anyone into thinking they're real, you can act like a self-centered jerk and see if anyone believes you're really him.
