The 10 most popular Halloween costumes according to Google, plus a few more obscure ones we found with its new Frightgeist tool

Not only are witches cool, this costume is pretty easy to put together. Modern witches don't even need pointy hats. 

Make it more unique: Choose a specific witch, be it someone from "The Worst Witch," "The Craft," or "Chilling Adventures of Sabrina." "Hocus Pocus" is probably going to be a popular choice.  

A versatile choice, dinosaur costumes can either be cute or frightening. 

Make it more unique: The T.rex is always very popular, but we think the stegosaurus, triceratops, or ankylosaurus should get some respect, too.

It makes sense that Netflix's eerie series is all the rage when it comes to Halloween costumes. Not only is the show wildly popular, you can get away with wearing jeans and a t-shirt (as long as it's the right t-shirt). 

Make it more unique: Recent seasons have given us many iconic and easily identifiable characters, but maybe harken back to season one and don a bunch of Christmas lights or Eleven's pale pink dress.

Kids and grownups who love glitter and wings gravitate toward fairy costumes. Grab some tulle and maybe a wand, and you're pretty much good to go.

Make it more unique: Do you also love Christmas? Pull together a sugarplum fairy ensemble.

The web-slinger's look is basically a one-piece, so you don't need too many accessories. That frees your hands up to hold a treat bag. 

Make it more unique: Get a friend to wear the same suit and re-enact that meme of two Spideys pointing at each other.

A costume you can reuse around Easter? Makes perfect sense.

Make it more unique: Get yourself a pocket watch and bow tie in homage to the White Rabbit from "Alice in Wonderland."

No matter what she's wearing, this Batman villain is always striking. 

Make it more unique: Harley's had a variety of looks over the years, but her multi-colored hair makes her pretty recognizable. 

Who doesn't love an excuse to call their friends "matey" and say "arr" every 90 seconds? 

Make it more unique: Style yourself as a movie pirate who illegally downloads films. 

If you're going trick or treating, a costume that requires sneakers is always a plus.

Make it more unique: Go as a ghostly cheerleader because you've got spirit, yes you do! 

Many, many people already have everything in their closet needed to pull off this costume. 

Make it more unique: Borrow John Cho's slick "Cowboy Bebop" style.

If you want to stand out from the crowd, we played with the Google Frightgeist tool to get some unique recommendations you're unlikely to run into at your next Halloween party.

If you're in the US and hear hooves, think horses not zebras. If you want a costume that's a bit more unique, zebras are ranking #589.

If you appreciate a pun, you're slightly less likely to run into another knife-wielding breakfast staple, ranked #829, than a fellow French Kiss, #800. Attach some mini cereal boxes to your shirt, grab a fake knife, and your costume is all set.

Ranked #554, there's a decent chance your Halloween party won't be overrun with other international criminal masterminds.  

We didn't say this "Wizard of Oz" costume, which ranks #832 in Google's list, would be easy. But you'll probably give some fellow revelers flashbacks to terrible dreams they had as kids.

If you want to be a superhero but not the same one as everyone else, Green Arrow is currently ranking #835. That's surprisingly even lower than Green Lantern, #720.
