Appealing Banana Costume Adult Deluxe Set
A banana costume is the kind of thing you never know you wanted until you see a picture of one. While it might be an unconventional choice as a Halloween costume, the end results speak for themselves.
This banana costume not only has a (reasonably) realistic banana to wear, but the banana can be "unpeeled" at the top if you're getting too hot and need some air.
White Ghost Costume For Women
Sometimes, simple costumes are the best. For those who want to dress up a little bit for Halloween but don't want to squeeze into uncomfortable clothes or wear a mask, this ghost poncho is a great option.
This costume consists of a flowing white poncho with a hood crafted out of 100 percent polyester. It has some stretch and is easy to wash and clean.
Adult Scream Mask
The Scream franchise doesn't have the cultural cachet it once did, but the iconic mask from the series has become a symbol of its own. You can get your hands on this mask for a great price on Amazon.
The mask is made of white foam with a black material that allows you to see out without others seeing in. It's all completed by a black shroud that surrounds the mask itself.
Tunic Hooded Robe Costume
This cape/tunic/robe/whatever you want to call it offers a simple and spooky vibe for any number of Halloween costumes.
While it looks great on its own, it could also form the basis for other Halloween costumes when paired with a mask or other accessories. A brown option is also available if you want to channel spooky monk vibes.
Plague Doctor Mask and Cloak
The events of 2020 might have made many of us hesitant to ever discuss plagues again, but that doesn't change the fact that medieval plague doctors offer up an aesthetic that perfectly fits the spooky season.
This high-quality plague doctor mask has a faux-leather beak and two eye holes to see out of. The ensemble is paired with a cloak and balaclava.
Peanut Butter and Jelly Couple Costume
If you and your partner are heading to any Halloween parties this year, it only makes sense to wear complementary couple's costumes. While you could each make your own, you could also save the hassle by picking up a ready-made couple's costume.
This simple set includes one "peanut butter" and one "jelly" costume. It's up to you who wears which. The most important thing is that they go together like PB and jelly.
Owl Adult Onesie Pajamas

Aside from the classic ghost, the skeleton costume — a white skeleton design on a sheer black costume — is an all-time great Halloween option.
This high-quality skeleton costume has everything you'd expect and then some. It's a jumpsuit with a hood that zips up fully over the face to provide a full "skull" effect. The transparent eyes will help you see out. There are even a couple of different color options available.

It can be dressed up or down with leggings or jeans, and its cozy fleece design ensures comfort and warmth this spooky season.
Men's Get Real Beer Pint
It's a cliché that many men turn beer into a personality trait, but it's a cliché for a reason: It's often true. If you're one of these men, embrace your inner hophead with this awesome beer costume.
The front of the design features a hyper-realistic depiction of a glass of beer, complete with condensation on the outside. It looks good enough to drink.
Clown Inflatable Costume
Clowns are generally regarded as creepy more than entertaining in the 21st century, thanks to horror literature like Stephen King's It. If you're trying to de-creepify clowns, or if you just want to lean into that spooky factor, check out this inflatable clown costume.
While this clown looks friendly and approachable, it's entirely possible to turn this into more of a horror clown with the use of accessories.
Punk Mask Cosplay
People seeking Halloween costumes and aspiring anonymous DJs will find common ground with this impressive light-up mask. The black visor allows the wearer to see out without anyone seeing in, and the light-up red triangle is certainly eye-catching.
The mask is created using high-quality materials and wraps fully around the head (and down the neck), ensuring full anonymity for anyone who wears it.
Women's Deadly Ninja Costume
Classic costumes are classic for a reason: They look good, and they stay fresh because they're not tied to any specific franchise or current trend.

Sometimes, you just want to unsettle people with your costume. If that's your goal this Halloween, consider this full face latex mask depicting a scowling old lady (complete with a cigarette in her mouth).
The mask comes in at an impressively deep discount, especially considering how good it looks. The level of detail almost make it look like movie makeup, which isn't something you can say for many Halloween masks.
Women's Gothic Red Riding Hood Costume
It's a trope that every possible Halloween costume has been made sexy, and while there's truth to that, there's also nothing wrong with embracing this spirit when dressing up.
There are about a million different ways to envision a Little Red Riding Hood costume, and this is one of the better applications we've seen. This satin dress is appropriately red, and incorporates an intricate venice lace throughout its construction for a truly eye-catching look.

Women who are looking for a fun costume that doesn't stray too far from their comfy everyday wardrobe of jeans and a t-shirt should consider this Wonder Woman costume.

Adult Pickle Costume
Are Pickle Rick jokes and references played out? The answer may very well be yes, but that shouldn't stop you from picking up this adult-sized pickle costume simply for its fun and novelty value.

This might not be the most practical wardrobe for everyday wear, but for Halloween (or costumes or other fun dress-up scenarios), it's certainly a head-turner.

The nice thing about dressing up as the Scooby Doo gang is that you don't need licensed apparel or specific logos — you just need regular clothing in the right cut and size.

Oktoberfest and Halloween are both autumnal activities, and the distinctive outfits worn during Oktoberfest lend themselves extremely well to a Halloween costume.

Slim Fit Adult Giraffe Onesie
This giraffe onesie is cut a little closer to the body than other similar onesies, so it's a great option for those who want the convenience of a onesie but don't want to look like they're wearing a sack.
While you're looking at a giraffe-themed onesie, this lineup comes in a number of different animal themes, so it's worth checking out the other options to find your favorite.

The nice thing about these LED masks is that they're so eye-catching that they're essentially a costume in themselves. You can wear a standard hoodie and jeans with them and it won't matter, because everyone is so transfixed by the mask.
This mask can display all sorts of colors, patterns and designs, and can even be programmed so you can display certain emotions or expressions in response to what's going on.
Inflatable Adult Cowboy Costume
We're not sure what to call this genre of costumes — the type where it looks like a two-person costume, but it's only worn by one person.
Whatever you want to call them, they're a classic for a reason. This fun cowboy costume is a great buy for anyone who wants to be a rootin' tootin' cowboy but also doesn't take themselves too seriously.
50s Pink Lady Satin Jacket

Dreamgirl Adult Dorothy, Blue Gingham Dress Costume
The Wizard of Oz provides all sorts of potential for costumes, from the Wicked Witch to the Tin Man to the Cowardly Lion. Dorothy outfits are also popular, of course.

Adult Butterfly Wing with Lace Mask and Black Headband
This pretty butterfly costume incorporates the colors of the monarch butterfly, perhaps the most iconic butterfly out there. The flowing wings stretch outward with your arms, and fold back in when your arms are at your sides.

The mask is powered by a pair of AA batteries and can display three lighting modes. Pick up a mask and gloves in the same color to sync up your Halloween light show.
Glamour Witch Costume
A witch costume has to be in the top five of all-time classic Halloween costumes, and this particular outfit puts its own spin on the classic theme.
While this is undeniably a witch costume, the purple satin flourishes on the robe and hat give it a sense of unique character. Pair it with a broom and you're ready to go.
Inflatable Cow Costume
Inflatable costumes are going to make you look bigger than you are, so it makes sense to theme these costumes after big things — dinosaurs, cows, and the like.
