Space. The great unknown. The wise minds of Stephen Hawking and Carl Sagan think that aliens exist out there somewhere, and who are we to argue with a bunch of science experts like those guys. In fact, we like to celebrate the idea of space aliens with costumes based on some of the extra-terrestrials imagined up by mankind over the last few hundred years and the astronauts who'll probably end up having to fight them in the ensuing galactic battle against them.

This year, find the perfect alien Halloween costume. Each of our alien costumes highlight a different type of extraterrestrial look. Whether your dream is to be a little green man who scares the living daylights out of all of your neighbors, a xenomorph from the Alien movies or the loveable Alf, we got you covered. Full body suits, masks, accessories and everything in between; that's the kind of arsenal we're packing when it comes to life beyond Earth.

Alien Costumes for Adults

Calling all fans of extraterrestrial tales! If you've been tuned in to UFO shows on TV, have watched alien flicks in the theater, or have poured over extraterrestrial accounts in too many books to count, then there's probably something that you're long overdue for. It's time to go in an alien costume for Halloween! We've got fantastic costume options for you to choose from, and we've picked out some of our favorites below. Whether you're a casual pop culture fan or a serious believer, we're sure one of these fun alien outfits for adults will be an entertaining choice for a great costume experience.

Alien Costume for Women

Alien Costume for Women

Cosmic alien beauties may be a bit of a B-movie trope, but we don't think that's any reason to look past this Galactic Babe Alien Costume for women! There's a lot of fun that's to be had by dressing as a sexy alien, so we say go for it if you feel so inclined. Made By Us, our costume designers went all out in adding its extraterrestrial looking features. Styled to look like a skimpy romper and hot pants, the silver foam pieces are worn over a green shirt and leggings. You'll appear like you've got the green skin of a sentient species from a faraway planet! The silvery finish of the suit along with shoulder and hip flares give it a sexy, stylish look. A must-add to this costume is our glitter space buns wig, it's the style we have pictured, and it will have you looking like one hot E.T. mama! You can also add a green alien mask or alien costume makeup to continue the "green-skin" effect, but that's totally up to you. This costume's complete out of the package and will have you ready to be the intergalactic babe you were always meant to be!

Plush Alien Costume

Plush Alien Costume

Accounts of "little green men" are mostly of pop culture origin, since most purported alien encounters leave witnesses reporting silvery-gray colored aliens. But no matter. The little green alien is the iconic look of an extraterrestrial species that comes to mind when you talk about alien species. If you'd like to be a green alien for Halloween, it's a great choice! There's nothing to worry about being "little" if you happen to be an average to tall-sized human. Made By Us, our lightheartedly designed Green Alien Costume is sized to fit average-sized adults, so that even men standing at 6 feet and taller can be little green men, too. This loose-fitting velour jumpsuit comes with a plush oversized foam headpiece that will transform you into a nonhuman creature of extra-earthly origin. (Not literally, of course.) It even has attached gloves with circular fingertips for added alien effect. It doesn't come with the blaster we have pictured, but we do recommend adding a ray gun prop toy so that you can blast bystanders with your pretend cosmic rays. Pew-Pew!

Inflatable Alien Costume

Inflatable Alien Costume

No doubt about it, the top alien outfit from the past few years has been large and in charge. Because this Alien Carrying Human Costume has been a top-seller and has gotten rave reviews from our customers! Alien suits are usually picked as a funny costume choice for Halloween, but this is the one that takes it over the top. Featuring a clever design from the costume masterminds at Morphsuits, this costume brings home an alien abduction costume theme that everyone can't help but chuckle at. That's because the costume suit fits around your neck to make your "human" body look like a short figure suspended in mid-air. Below the waist, your legs are a part of the green alien body that's attached to the back of the person. The very-grabby alien has a super-sized head that towers above your own, and it's got its long arms wrapped around the torso of the figure. The sleeves for your arms are attached to the person so you're able to wave them around for dramatic effect. But it also helps when holding your favorite beverage at the party. That's assuming your green E.T. pal is accommodating for that!

Area 51 Alien Costume

Area 51 Alien Costume

It doesn't matter how many times it's been debunked, there are always UFO believers convinced that Area 51 holds all the secrets to the alien phenomenon. The myth persists thanks to reinforcement in pop culture media like The X-Files and Independence Day. With plenty of conspiracy theories persisting to this day, we say if you can't convince them, then you might as well roll with it. And you can do that in a big way with this Area 51 Alien Costume! This witty costume pairs a prisoner style jumpsuit with a frightening alien mask, so you can look like an E.T. who's been stuck in the top-secret facility for quite a while. You could even play up the idea that you've been held there since 1947...but no matter how hard you try, you can't get those military scientists to understand your flying saucer technology! We're sure that would make for one alien who's really ready to cut loose and party.

Kid's Alien Costumes

Alien costumes are always a go-to choice for kids looking for something out of the ordinary for a Halloween theme. And these alien costumes for boys and girls are so extraordinary, they're out of this world! We have fantastic alien outfit choices for kids, including exclusive Made By Us designs, plus some of the top curated choices from costume makers worldwide. So check out these top sellers, and see if any of them are the one that will have your kiddo ready to blast off for a great time!

Friendly Alien Costume

Friendly Alien Costume

Aliens don't always have to be the bad guys! With this Friendly Alien Costume for kids, we imagined a fun-loving alien with an easy-going disposition when we designed it. It's even got an extra set of arms, so the friendly alien can give out extra-large hugs! Kids are sure to love the exotic styling of this Made By Us costume, too. With the plush arms and headpiece and shimmering silver jumpsuit, it's sure to have them jumping for joy and ready to imagine an interplanetary adventure this Halloween.

Cute Alien Costume

Cute Alien Costume

Girls can get into the UFO fun for Halloween, too. They can do that with any of our alien jumpsuit costumes, of course. But if they'd like an E.T. look that's a tad more glammed up, they can be a cute alien who's just touched down on Planet Earth with this Outer Space Cutie Alien Girl Costume! This fun costume is designed as a dress with a pink and silver PVC finish, with attached green sleeves for alien skin effect. The matching pants continue the green skin concept, and it comes with a belt, gloves, and a pom-pom antennae headband to complete the outfit.

Alien Assassin Costume

Alien Assassin Costume

Some kids will want to be a little more intense for Halloween, and a few boysmay even be intent on starting an intergalactic war. That's just fine, too. Because we can make your kiddo a major player in an alien invasion when we get them into this Alien Assassin Costume! Your child will look like a combat-ready soldier of an alien army with this outfit. Featuring an eerie green E.T. mask and a remarkable robe that looks like it was crafted with fabrics not of this planet, it's set for all-out alien battles!

Alien Piggyback Costume

Alien Piggyback Costume

Another top choice for kids is this hilarious Alien Piggyback Costume. This fun costume doesn't imagine an alien abduction, but rather imagines a cosmic being ready to give your kiddo a lift around town on his shoulders! With fiberfill features, this costume is easy to wear, too. Just pair it with any shirt and sneakers, and it cinches around the waist for easy costume effect. If you've got a couple kiddos to suit up for trick-or-treating, be sure to shop all of our Ride On Costumes for a fun child group theme!

Alien Halloween Costumes from TV and Movies

Science fiction TV shows and movies have been popular for decades, so it makes sense that our top space alien costumes come straight from the most memorable pop culture selections. With men's alien costumes and alien costumes for kids featuring fan favorite characters and ferocious antagonist aliens, we definitely have an alien costume idea that's perfect for your science fiction fandom.

Toy Story Alien Costume

Toy Story Alien Costume

Tons of Toy Story costumes have helped fans relive their favorite moments at Halloween, but few have been as popular as the Pizza Planet Aliens. Well, save for Buzz and Woody, of course! The cute squeaky toys have been seen in each Toy Story movie, so you're sure to be recognized in this iconic Inflatable Toy Story Alien Costume. Be sure to get three if you can get together a costume trio to maximize your movie-inspired fun. Ooooh!

E.T. Costume

E.T. Costume

The pop culture impact of Steven Spielberg's E.T. has been massive since it debuted in 1982, so it's no surprise that kids today are still connecting with the film's timeless themes. We can even get your kiddo involved in the fun by getting them into this E.T. the Extraterrestrial Costume for kids! Made By Us, this plush suit is designed to be a faithful recreation of the alien character, plus it's officially licensed so you can be sure we made it with authentic fun in mind.

Alf Costume

Alf Costume

Everyone's favorite boorish alien being made a big impact across the airwaves of TV in the 1980s when his spaceship crashed in the garage of the Tanners. We're talking about Alf, naturally! And whether you grew up with the show or became a fan after watching reruns, we're happy to get you suited up as the iconic TV alien with our exclusive Alf Costume! Our officially licensed design includes the alien mask with Alf's signature snout plus the furry suit. It makes for instant sitcom fun.

Predator Costume

Predator Costume

When it comes to scary aliens, there's been quite a few of them featured in movies about extraterrestrial takeovers. But perhaps the scariest doesn't come to Planet Earth to take over, he's just stopping by to hunt trophy humans! The Predator has been an iconic alien character since 1987's Predator, with the intense action spawning plenty of sequels along the way. So it's safe to say it will be a whole lot of ferocious fun for you to go as the fearsome hunter this Halloween!

Love Your Look: An Alien Invasion!

Love Your Look: An Alien Invasion!

When the time comes for kids to set up an alien abduction costume scene, it's probably the best bet to have some child astronaut costumes. That way, the kiddos are suited up and ready to deal with the Martian's strange alien technology. They can build a rocket playset out of cardboard, like we did here, and set the whole fun scene up! Our extragalactic alien looks fantastic with his soft velour costume suit. The plus alien mask does the trick, too, with creepy effect from the black see-through eyes and probing antennae attached to the top of his head. Our brave child astronauts are ready for the encounter, though! Aside from having a rocket ship hand-decorated with markers and paint, they each have one of our Made By Us astronaut costumes and are ready for action. That means they'll be able to take on the extraterrestrial being here on Planet Earth, to blast off and find the alien base on the moon. Or they can even have a zero-gravity showdown in outer space! The adventure is only limited by their imaginations because our awesome costumes will take care of the rest. Come to think of it, maybe it'd be best to have them take some of the gear off and have a snack before they battle it out. Because this alien invasion is going to be so much fun, it could last for hours!
