Adult Costume Ideas

So, you're all grown up now. You've graduated from the wondrous world of being a kid into the world of responsibilities. You've got bills, maybe you have a fancy job and maybe you've even got yourself a family, but that doesn't mean you have to pack your imagination away in a box in the attic. Quite the opposite, actually! Now that you're an adult, you deserve a break from all the responsibilities and hassles of life more than anyone. Why not dress up in one of our adult costumes to party like it's your birthday (even if it's not really your birthday). Check out these tips and ideas to jump start your leap into a fun and memorable costume experience this year.

Adult Costumes for Parties

Remember being a kid, when you were forced to sit at the kid's table? You could only imagine what kind of grown-up stuff was happening at the adult party. Now that you're an adult, you can make your party something beyond the wildest imagination of a kid, because you can do what you want! That's beauty of being an adult, despite all the responsibilities that come along with adulthood; you also have the resources to throw one of the coolest costume parties in existence. So, let's get started with a few great adult costume ideas to wear to an awesome costume party.

Greek Goddess and Toga

Greek Goddess and Toga

Classic, regal and...who are we kidding? Toga! Toga! Toga! Nothing quite sparks the party spirit like the look of the ancient Greeks. Made famous by fraternity houses, the toga has a lot of things going for it. The look is quick and simple, with a whole plethora of easy ways to accessorize. If you want to go all out, you can grab some sandals and gold wreath crowns to look like Greek royalty, or you can simply toss on the toga. And all it takes to get the party started while wearing this costume style is to simply shout the word, "Toga!" and repeat ad nauseam.

Great Gatsby

Great Gatsby

Depending on who you ask, The Great Gatsby is F. Scott Fitzgerald's masterpiece novel about passion and the great American Dream, or it's a movie starring Leonardo DiCaprio. Whichever version you prefer, there's no denying that the 1920's makes for a great party theme. All it takes is a little bit of jazz music, our flapper dresses, and some dashing suits to make your party feel like the speakeasy throwback you've been yearning for. And since prohibition no longer exists, you don't have to worry about the cops coming to bust up your fun.

Murder Mystery

Murder Mystery

How about the game, Clue? The question on everyone's mind is, "Who done it?" Of course, the correct guess is always Professor Plum in the wine cellar with the stapler. (Professor Plum is always up to no good.) Well, the board game is not only a fun way to pass time with the family, but also a great inspiration for costume themes! With plenty of maid, British constable and safari costumes, each person in your group can dress as a slightly suspicious character in your English country house murder mystery. It's the kind of party your guests won't soon forget.

80's Party

80's Party

Ahh, the 80's. Who could forget them? The florescent colors. The teased hair. And, of course, the strange obsession with listening to oldies while engaged in strenuous physical fitness. If there was ever a valid reason for hopping into a time machine, the 80's are it. It's the go-to party for anyone who wants to practice their Thriller dance, or anyone who wants to bust out the Cyndi Lauper tunes. There are plenty of styles to sate your hunger for a retro theme. Will you go as the mall-obsessed valley girl, the moonwalking pop star, Michael Jackson, or the poofy haired workout icon?

Egyptian Party

Egyptian Party

Egyptians did a lot of things right, like pyramids, hieroglyphics and pharaohs, and let's not forget the most famous queen of them all, Cleopatra! They probably knew how to throw one killer party back in the day, but since time machines don't exist, you'll just have to use the best of your imagination. With an Egyptian themed party, you can dress everyone up in luxurious golds, wear extravagant headdresses and, of course, you have the perfect excuse to get out your old Bangles albums so you can crank “Walk Like an Egyptian.” That's a cause for celebration in and of itself.

Renaissance Party

Renaissance Party

It's time to party like it's 1599! Something about history is just, dare we say it, fun? A medieval themed party is always a great way for you and your friends to express your inner knight or princess. You can have your own Renaissance Festival in your backyard, drink some mead and hearken back to the days when you had to make your own candles instead of just buying them online. You can perform deadly duels of the sword, or just simply proclaim yourself to be a master blacksmith! Just make sure you dress for the part in one of your adult Renaissance costumes.

Adult Cosplay Ideas

"Halloween" can be a dirty word for a lot of cosplayers. Many costumes designed for the annual holiday don't always have the high level of intricate detailing that the average cosplayer needs. Not only that, but part of the satisfaction of cosplay comes from the hard work and effort you put into creating your own little touches on the character. These adult costumes are a starting point for any aspiring cosplayer, with a higher level of detail than many costumes. You can still get that homemade satisfaction by adding your own accessories and the finishing touches to it.

Attack on Titan

Attack on Titan Costumes

While we wouldn't want to live in a time where Titans rampage through the countryside, it does make for a pretty good story... and costume for that matter. Our licensed Attack on Titan Costumes come with a high level of detail, like Survey Corps emblems on the back of the coat, so they make for the perfect way to begin your Eren Yeager cosplay outfit. You're going to have to bring your own sense of unbridled anger to complete the full character effect.

Doctor Who

Doctor Who Costumes

Whether you just started watching, or you've been catching episodes of your favorite Time Lord for decades, Doctor Who makes for one great cosplay option. Of course, the first thing you need to bring to the table is the Doc's undeniable swagger. Depending on which one you chose, that could mean many different things. That could mean carrying a bag of Jelly Babies around with you, or it could mean wearing a fez hat. Either way, you can find the beginning of your costume right here.

Marty McFly

Marty McFly Costumes

In 1985, Marty McFly epitomized the word "heavy." These days, he still does. The classic character just never goes out of style, but that's because great movies never go out of style. His signature outfit might have been easy to find in the 80's but these days, his vest, hairstyle and slang terms, just aren't that easy to come by. Luckily, we've got an exclusive costume based on his appearance from the movie, so you can transform into the character with relative ease for your next cosplay event. That is indeed, "heavy."

Chewbacca

Chewbacca Costumes

Anyone who's ever tried to make their own authentic Chewbacca cosplay will probably regale you with a tale about how hard it is to sew that much fake yak fur onto a costume. The good news is, they already made an authentic Chewie costume. Although it might not give you the mannerisms of Peter Mayhew, it will get you started in the right direction for an authentic Star Wars cosplay experience. You can spend all the time you would've spent sewing, creating a sweet bowcaster replica. Or working on your roar.

Jon Snow

Jon Snow Costumes

Holy smokes! Jon Snow has been through quite a bit. Legitimacy hate, problems with white-walkers, friends pretending to be enemies and enemies pretending to be friends. He's really seen it all during Game of Thrones. Our replica costume helps you attain the role of protector of the north with ease. All you need to add is your own legendary sword, your own cunning and a bit of warfare know-how to get your Game of Thrones cosplay started.

Sailor Moon

Sailor Moon Costumes

She's the one called Sailor Moon and she's a pretty big deal. Sailor Moon is a classic when it comes to anime, so she's a staple in comic con crowds. That makes her an easy pick when you're trying to put together a great outfit to wear for a bit of cosplay. It won't give you any of the powers that she normally has, but it will get you quite a few positive comments when you head out wearing it. Just make sure you're rocking the long blonde pig-tails!

Adult Comic Con Costumes

Not everyone wants to spend hours crafting the perfect, 100% accurate costume based on their favorite movies and comics. So, what happens if you're an adult that wants to show up at a comic-con as their favorite Futurama character, but you just don't have the time or know-how to get it made in time? It's a piece of cake! Many of these costumes, like our Zapp Brannigan costume, help you achieve the image of your favorite character right out of the package. That means all you have to do is put it on and listen as the geeky convention goers cheer you on. Check out some of these easy-peasy ideas for your next convention trip.

Mario and Princess

Mario and Princess Peach Costumes

Going to comic-con as a couple? Mario and Princess Peach are the video game power couple to be! Those two have been going strong for over 30 years, so they're a classic couple at this point. He can work on his plumbing skill, and she can work on her go-karting techniques. It’s good to have hobbies when you’re a couple!

Evil Queen

Evil Queen Costumes

Villains are always a great choice for comic conventions. They let you embrace a little bit of your dark side for the con and let's face it, being a little bit bad is far more fun than being good! This Evil Queen has a look inspired by the classic Disney tale, Snow White, so you know it has a classic evil look that everyone will remember. People may not trust any apples you try giving to them though.

Beetlejuice

Beetlejuice Costumes

Beetlejuice! Beetlejuice! Wait, it's not good to say that three times in a row! This costume idea comes from the classic Tim Burton film. There are a lot of different routes you can take with this one, but all of them lead to a good time at your next comic-con. Just make sure you pack a few one-liners to get you through the day.

Harley Quinn

Harley Quinn Costumes

A thorn in Batman's side and the Joker's main squeeze, Harley Quinn is a robust character ripe for comic-con. Since she's a bit kooky, or well, more accurately put, she's completely loony, she makes for a great way to get a little bit crazy at comic con. With various styles to choose from (comics, video games, cartoons and film), you can take this look in any direction you please!

Captain Planet

Captain Planet Costumes

"Earth, fire, wind, water... heart! By your powers combined, I am Captain Planet!" Sure, the heroes were kind of cheesy and the villains were even cheesier, but that's kind of what makes Captain Planet awesome. That and the positive pro-environment messages that it sent to kids back in the day. Everyone remembers him and he makes for a great costume to wear to your next comic convention. He IS our hero, after all.

Zapp Brannigan

Zapp Brannigan Costumes

Last, but certainly not least, we have Zapp Brannigan. He's the all-star ship captain for DOOP and he might be one of the best ways to head to a con. As a fan favorite, not only will you have great interactions with other fans, but you'll have a chance to do your best Billy West impersonation to say some of the funniest lines from the show.
