Do you know what is spookier than spooky season? Parenthood. It doesn't matter how much you prepare for it, it's filled with unexpected twists and turns. It's your job, as a parent, to figure out how to take care of your mini me as best as you can! Don't let that scare you too much, though; becoming a parent is a lot more fun than you think.

For example, if you are the expecting mom, you get to use that big ol' belly to your advantage! This Halloween is way more different than any of your Halloweens before you started creating a lil body inside of you, but it can be the most fun. There is so much you can do with your new, growing body. Get creative! You can still look hot, you can still look scary, you can still look funny, heck, you could even still look niche! Whatever you want, the world if your oyster! In fact, here's an idea: be an oyster, and your belly can be the pearl! See? Let's keep this brainstorm going!

01
Goldfish in a Bag

This one is actually easier than it appears. You can either buy a dress that has a goldfish on it, or just buy a goldfish patch and put it on whatever you want to wear underneath a clear trash bag that you cut leg holes in.
02
Tony Soprano

Only the real ones will get this right away, but Tony Soprano is the perfect cool and comfy costume for any mom-to-be who's a fan of The Sopranos.
03
Gumball Machine

This one is also not as complicated as you might think! You can buy a mixed bag of colorful mini pom poms and glue them onto a shirt around your belly, or just paint a bunch of different colored circles on a shirt. That's it! Have some gumballs to give out too, if you want to go a step further.
04
Mike Wazowski from 'Mosters Inc.'

You probably loved Monsters Inc. when you were a kid! So might as well get your little one prepared to watch it once they join you in the world.
05
Boozehead

via alvababymx

This one is hilarious, IMO, but some people might get offended. Between you and me, though, that sounds like a them problem. If you do this, you're friggin' funny and we are friends!
06
Rihanna at the Super Bowl LVII Halftime Show

This is for the legends, the icons, the baddies. Embrace your amazing energy by dressing up as Riri herself!
07
Rey and BB-8 from the 'Star Wars' franchise

via alvababymx

I don't care what you say, Star Wars is and always will be a classic. Even if Disney has been taking it too far!
08
Juno and Paulie from 'Juno'

This one will really warm the hearts of millennial parents. Dress up as one of the most iconic couples from this beloved, popular early-aughts indie film.
09
Bob Ross

There are no mistakes, just happy accidents! You might have to watch an episode of The Joy of Painting to be able to paint a masterpiece on your belly, but it will be fun either way!
10
Out of shape Thor

This is one for the Avenger fans! Easy and geek-chic.

You are creating life! You and Mother Nature have something in common.
12
The Handmaid's Tale

If you want to make a statement, then this is most definitely the costume for you!
13
Kourtney Kardashian and Travis Barker

via beigehavenco

This one is hilarious, but also for the baddies. If you remember this iconic moment in pop culture history, you're a real one.
14
E.T.

Throwback to the '80s with this classic movie reference from E.T.
Isn't this fun! Soon you'll have to think of costumes to match the little one. I had a friend recently who had a baby girl, and when she got a little older, she wanted to be the Catbus from Totoro. Now, if you have seen that movie, you know that this is not an easy costume to make. But moms can do anything! She not only made her an epic Catbus costume; she and her husband also dressed as characters from the movie. See? Halloween just gets more and more creative every year of parenthood. How fun for you mamas and papas!
15
Miley from the "Wrecking Ball" music video

via heyitsjenna

You came in like a wreeeeeeecking baaaaaaall! But the wrecking ball is your preggo belly. Cute and catchy!
16
Disco Ball

You can really boogie down with this disco ball costume! Better start working on those moves. Maybe choreograph something with your partner.
17
Basket Ball

Some moms are sports fans too! So dress up as your favorite sports ball. Here we see the orange one!
18
Ignacio from 'Nacho Libre'

via lexus_armour

Another classic indie film us millennials will never forget! Plus, Jack Black is our hero.
19
Eight Ball and Pool Shark

via carmelisse

If you really want to have fun with this, you should have your partner add a shark fin to his fit to be a pool shark.
20
The Lorax

via asa_howard

You speak for the trees! This one is extra funny because the kids who have seen the movie will love this, but the kids who haven't will probably be terrified.
21
Fortune Teller and Crystal Ball

via beautilandbylexii

You can see the future: it's your due date!
22
Charlotte and Big from that one scene in "S** and the City"

via catquinn

This scene was what brought the most annoying couple back together. Hot take? Whatever. I can agree, at least, that those characters were all really great friends.
23
Full Moon and Astronaut

via sonnyloops

Parents to baby, come in, parents to baby! You could also wear a galaxy fit like that print that had us all in a chokehold back in 2010.
24
Dirty Martini

via MaybeImABean

This woman is not knocked up in this picture, as far as I can tell. But I couldn't find a mom-to-be online who has done this costume… Which is crazy because there is no way I invented this! But yeah, paint your tummy like an olive, make a little triangle frame to wear on your torso, and there ya go! You're a dirty martini with a cute lil olive.
