2 comments

If you’re a nerdy mom, there’s a good chance you also love Halloween.

It’s the one day of the year it’s acceptable to dress like your favorite characters from the movies, TV shows, video games, or books you geek out over (unless you are a cosplayer of course, in which case you dress up all the time!)

Hopefully you’ve passed on the geeky gene to your kiddos; then the whole family can dress up together!

Here are ideas for kids and families to get their nerd on this Halloween:

1. Guardians of the Galaxy

How cute would a Baby Groot costume be for the baby in the family? Guardians of the Galaxy can easily work for the whole family with Dad as Starlord, Mom as Gamora, and an older child as Rocket.


2. Star Wars

If you’re a Star Wars fan, there are a lot of Halloween costume options. Kiddos dressed as Ewoks would be just adorable:

If the kids are Ewoks, mom could go for Princess Leia on Endor. A green poncho with Leia’s braids would make this an easy one for mom!

There are so many options for the family, depending on which trilogy’s characters you want to dress up as. Rey, Kylo Ren, Yoda, and BB-8 are some popular ones right now!


3. Avengers

The Avengers offer a lot of possibilities for Halloween costumes. Our family is doing Avengers this year, with my husband as Thor, me as Black Widow, my son as Iron Man, and my daughter as Captain Marvel.

The Hulk, Spider Man, Captain America, Shuri are all awesome as well.


4. Justice League

Maybe DC is more your style. Have the parents dress up as the villains (Joker and Harley Quinn) and the kids dress as the heroes (Batman and Wonder Woman).


5. Hobbits

Lord of the Rings fans have a lot of Halloween options too, but a whole family of hobbits would be something different. Something for Mom, Dad, kids, and baby.


6. Mario

Here’s one for the gamers! Mario, Luigi, Princess Peach, and Toadstool!


7. Zelda

Another one for the Nintendo fans. A Link and Zelda mom and baby costume would be cute and nerdy.


8. Pokémon

Mom and Dad as Misty and Ash, and the kiddos as Pokémon.


9. Toy Story

Disney nerds might like the cast of Toy Story for family costumes. Woody, Jessie, Rex, and Bo Peep.


10. Zombies

Looking for something a little scarier this year? Zombies can be as horrific as you want depending on how you do it. I was inspired by this father and daughter Halloween zombie photo shoot for this idea.

Here are some other father and daughter zombie ideas. Don’t forget your zombie blood!


11. The Incredibles

The Incredibles are a family of superheroes, making them an easy choice for a family costume idea, especially a family of five. Mr. Incredible, Mrs. Incredible, Violet, Dash, and Baby Jack.


12. Harry Potter

If your family wants to represent Hogwarts, why not try Dumbledore, Professor McGonagall, Harry and Hermoine.


13. Founding Fathers

Any history nerds here? Dressing up as important figures from the American revolution is a nerdy costume that is unique. George Washington, Ben Franklin, Abigail Adams, and Alexander Hamilton are some examples.


14. Greek Myths

Another great history themed costume for families would be figures from Greek mythology. The possibilities are endless, from the gods of the Pantheon like Zeus and Hera to famous mortals like Achilles or Psyche. The Roman versions of the myths work too, if that suits your fancy.


15. Futuristic Family

A lot of fun can be had making the whole family look like they’re from the future. Mom, Dad, kids, and baby can get decked out in spacy-looking suits and metallic colors for a general sci-fi look. You might even throw in an alien!


16. The Labyrinth

The Labyrinth was a 1986 fantasy film starring Jennifer Connelly and David Bowie that has since gathered quite a cult following. Sarah, Jareth, and Toby would make fun costumes for a couple with a baby! You could buy pre-made costumes, but this one would also be pretty easy to DIY.


17. Game of Thrones

You may or may not have liked the ending, but there were a lot of excellent and memorable characters from Game of Thrones that would make great costumes. You’ve got lots of options, but Daenerys, Drogo, and baby dragons would be cute for a family.


Well, there you have my ideas for nerdy and geeky Halloween costumes for kids and families. What are you and your family dressing up as this year? Any other great geeky costumes I missed? Tell me in the comments.
