If you’re celebrating Halloween in Las Vegas this year and you’re short on inspiration for a costume, all you have to do is take a look around you. From the marquees on Strip casinos to the advertisements on top of taxi cabs, there are no shortage of Halloween costume ideas inspired by Vegas shows. Whether you want to dress sexy, scary or silly this year, take your cue from the people in Vegas who dress up in costumes every night. These uniquely Vegas ideas are sure to be a hit.

For a Funny Costume: O Cirque du Soleil Clown
Cirque du Soleil’s iconic show O just celebrated its 10,000th performance at the Bellagio. Pay homage by dressing up as one of the scene-stealing clowns who garner audience laughs whenever they appear during the otherwise serious aquatic show. You can do this one alone or as part of a pair. All you need is a loose-fitting sailor’s outfit including the white cap plus white face paint, a red clown’s nose and oversized clown’s shoes. Pose in front of the Bellagio fountains for maximum effect.

Best Group Costume: Blue Man Group
Gather your friends and assemble this easy but instantly recognizable costume for a night of mischief. Dress in black and cover all exposed parts of your body in blue paint and you’ll look so much like the Blue Man Group that you may be asked to report directly to the Luxor. Because the Blue Man Group has shows in New York, Chicago, Boston, Orlando and Berlin in addition to Las Vegas, this costume will be effective just about anywhere in the world. 

Best Sexy Costume: Zombie Burlesque
Go for sexy with a dash of scary this year with a costume inspired by Zombie Burlesque at Planet Hollywood. All you need is lingerie, zombie makeup and an insatiable taste for human flesh. The show is set during the atomic era, so opt for a more vintage style when choosing your outfit, and don’t forget to smear on some fake blood.

Best Couples Costume: Penn and Teller
As the longest-running headliners to play in the same Las Vegas hotel, Penn and Teller are an important part of the city’s show business history. To capture the look of Penn and Teller—aka Penn Jillette and Raymond Joseph Teller—you and your partner can dress in pinstripe suits and carry props associated with the pair’s act at the Rio such as playing cards. Bonus points if the person playing Penn is able to grow a goatee.

Best Pet Costume: Piff the Magic Dragon
Piff the Magic Dragon of America’s Got Talent fame—and yes, that’s him on the cover of that Mumford and Sons album, too—has been a beloved figure during his residency at the Flamingo thanks in large part to his furry sidekick Mr. Piffles, a magical chihuahua who performs alongside Piff in a dragon costume. If, like Piff, you don’t go anywhere without your dog, go out this Halloween in matching outfits. All you need is a green dragon costume for yourself and one for your dog.
