If you are looking for great superhero costumes, dressing up like your friendly neighborhood Spider-Man doesn't get much better than this. 

Made completely out of spandex, this superhero outfit is perfect for Halloween, cosplaying or just web-swinging around town.

The costume comes in six different versions -- from the classic red-and-blue Spidey superhero suit to the Into the Spider-Verse-inspired Miles Morales getup.

An Amazon reviewer says that the costume is an "awesome product ... my son loves it."

Google predicted that Pennywise would be one of the most popular costumes of 2019. We found this version of the terrifying clown, dressed in the tattered stylings from the new It movies, available on Amazon Prime. Outfit includes the spooky mask.

But don't wait. This costume is selling out quick, and only some sizes are still available.

Because it wouldn't be Halloween without a sexy adaptation of an otherwise terrifying character, we present: The sexy sewer clown.

This four-piece ensemble is equal parts scary and sultry and will look great up next to your menacing, toothy grin. Don't forget to purchase the red wig to complete your look.

Do you want to look hot this Halloween? Taco Bell has you covered -- from your neck to your knees -- when you dress up as a packet of Diablo sauce, the chain's hottest hot sauce to date.

Taco Bell also licensed these hot sauce designs in Hot and Fire varieties. But those aren't available on Amazon Prime, so the shipping time could be dicey depending on how long you wait.

Dinosaurs won't be extinct while you're rocking this inflatable T. rex costume.

This ensemble requires four AA batteries to stay inflated and intimidating.

This is the king of cute Halloween costumes, and it currently has a four-star rating.

An Amazon reviewer purchased this prehistoric costume "for a friend ... and she loves it."

This unisex Gwen Stacy spandex jumpsuit comes in 11 different sizes for both kids and adults and you know, superhero costumes are always a hit. With advance notice, the seller also can make bodysuits in perfect custom sizes. 

One reviewer noted that "you can also use a touchscreen with the gloves," so you can Instagram Halloween night from start to finish. 

Don't leave your puppy out of the party (though you might need to bribe him with peanut butter to get him to join in). 

Who needs a doggy princess or unicorn costume? Dress your dog up like the freaking king of the jungle with this adorably cute and fierce lion mane.

The costume -- with a rating of 4.5 stars -- is labeled as a No. 1 best seller on Amazon.

An Amazon reviewer said, "This has been my all-time favorite Amazon purchase thus far." So what are you waiting for?
