1. Cruella & Her Pup
Now this is how you win Halloween without saying a word. @abbieherbert_ nailed the drama with her spot-on Cruella de Vil look—and the best part? That precious little dalmatian on her hip. The black slip dress keeps things chic and streamlined, while the feathered boa and red gloves dial the drama all the way up. And don’t even get us started on that split wig. Iconic.
What makes this so perfect is the duo moment—it’s fun, it’s unexpected, and it lets mama shine without compromising comfort. There’s something about embracing a fashion villain that feels very “I’ve got my life together” energy, even with a baby in tow. Halloween, but make it haute couture.
She gives us major “main character energy” here. Whether you’re heading to a party or just answering the door for trick-or-treaters, this costume is pure performance. And honestly, who knew Cruella could look this cute?
2. Pumpkin Belly Pop
Sweet, simple, and seriously adorable. @ariana_lee99 took the classic pumpkin costume and made it personal—literally. Painting the bump like a Jack-o’-lantern with the cutest pink bows is such a sweet way to include baby in the celebration. No complicated costume changes, just a black crop top and leggings to let that painted belly do all the talking.
It’s giving DIY in the best way. You don’t need to be a Pinterest mom to pull this off—just some paint, creativity, and a lot of charm. The bright pumpkin orange pops against the darker outfit, and the whole thing just feels happy.
Perfect for at-home photo ops, fall baby showers, or showing off your bump at a Halloween hangout. It’s one of those looks that proves you don’t have to go over the top to stand out. Just add a glowing smile and you’re the whole pumpkin patch.
3. Moonlight Magic
Moody, magical, and movie-poster ready. @bellynbaby.studio brought the full drama with this Halloween maternity shoot, and we are absolutely here for it. That long black gown, the flow of the fabric, and the full harvest moon backdrop? It’s like a maternity fairytale with just a whisper of witchy.
The gown hugs the bump perfectly, balancing elegance with just the right amount of spook. The bats in the background and flickering jack-o’-lanterns add to the eerie charm, but the overall vibe is soft and enchanting.
This look isn’t just a costume—it’s an experience. Ideal for moms who want something cinematic and timeless for their maternity photos. It’s spooky season meets goddess energy.
4. Skeleton Chic
Talk about ghostly glam. @chicagofamilydoulas glides into the room like the chicest phantom bride you’ve ever seen. The tulle overlay, the dramatic headpiece, and that subtle skeleton vibe all come together in one dreamy, gothic ensemble. Perfectly haunting, but still totally wearable.
It’s all about contrast here—soft and sheer layers over a sleek black base, giving the look major movement. The bump is the star, framed by delicate tulle and that perfectly placed floral accent. It’s dramatic without being fussy, which we love.
Whether you’re headed to a Halloween soirée or just love a themed maternity shoot, this one hits all the marks. Ethereal and theatrical, without feeling costume-y. Bride of Frankenstein, but fashion-forward.
5. Ursula Takes Over
Under the sea, but make it Halloween. @dressedtomatch went full Ursula and delivered a family look that’s bold, coordinated, and beyond adorable. The purple body paint, the fierce red lip, and that black strapless gown over the bump? It’s commitment, and it totally pays off.
Matching with the whole family (hi, Ariel, Triton, and mini Sebastian!) takes this costume to another level. It’s not just themed—it’s a production. But don’t be fooled by the elaborate vibe—Ursula’s look is surprisingly bump-friendly and perfect for moms who want to be part of the fun.
She proves Halloween is better when everyone gets involved. Bonus points for the crown-worthy confidence she exudes. Queen of the sea? More like queen of spooky season.
6. Spellbound Siren
@emilybrickel is bringing the drama with this full glam ghost bride moment. That long flowing dress is like a whisper in the night, with the dark tulle sash catching light in all the right ways. She’s got that haunting beauty look down—bold lip, big lashes, and a whole lot of “don’t mess with me” energy.
The fit is bump-flattering without looking overly tight or uncomfortable. It’s the kind of costume you could wear for a full evening and still feel like yourself—just with a little extra magic. And that haunted-house-meets-fashion-week backdrop? Flawless.
This isn’t just Halloween—it’s an entrance. A moment. A memory-maker. If you’re going for timeless spooky elegance, this one’s a winner.
7. Leopard Love
@jadelizroper said, “Why not go wild?” and we couldn’t love it more. This body-hugging leopard print dress is playful, bold, and perfect for showing off that bump with pride. The bright red glasses? Cherry on top. The whole thing screams sass with a wink.
It’s a no-fuss, all-fun kind of costume. You can throw it on in minutes and still look like you planned it weeks ago. The print does all the work for you, while the simple silhouette keeps things comfy.
This look works for any kind of Halloween plan—kid-friendly events, casual hangs, or a night out where you want to look cute and still move freely. Unleash your inner jungle queen, mama.
8. Meow-terly Purrfect
Leopard print and a bump? Always a good combo. @jennlahmers kept it sleek and fierce in a form-fitting onesie with built-in tail and ears to match. The fit is snug in all the right places and the print? Pure statement-maker.
This is for the mom-to-be who wants zero stress and max impact. Pop on the ears, add a smokey eye, and boom—you’re Halloween ready. Minimal pieces, major payoff. The green screen backdrop is a fun bonus if you’re taking pics or videos—it gives everything a studio-polished feel.
We love how easy this is to recreate with what you’ve got at home. Pair with heels or sneakers, go glam or spooky—it’s your call. Either way, you’re looking like a total knockout.
9. Dark Enchantress
@jessicasmithvisualarts went all-in on the dark enchantress vibe, and it’s basically Halloween poetry. The long, flowing black gown with bell sleeves feels like something out of a gothic novel, and the moody backdrop? Cemetery-chic at its finest.
This look leans hard into the eerie aesthetic without sacrificing any glam. The subtle makeup, the roses, the dramatic pose on the church steps—it’s giving Morticia, it’s giving magic, it’s giving maternity with major mood.
If you’re someone who loves spooky season and wants your maternity pics to scream “cinematic,” this one’s a must-save. Elegance with edge? Yes, please.
10. Grinch with a Bump
@katescookieskc came to sleigh—literally. This maternity Grinch look is as extra as it is hilarious, and we are obsessed. The full green bodysuit, fur trim, and that wildly expressive face paint? 10/10 commitment. It’s big on laughs and even bigger on holiday crossover energy.
The best part? It’s comfy. Stretchy fabric, cozy faux fur, and no tight spots around the bump. Perfect for dancing around the yard or snapping festive photos with the fam. And that top knot? So Grinch, so good.
This is one of those costumes that’ll have everyone talking. Playful, unexpected, and totally unforgettable. Halloween meets Whoville in the best way.
11. Pink Glow on the Porch
If color therapy had a spokesperson, it would absolutely be Kimberly in this hot pink number. The bump is bumpin’, the sneakers are crisp, and that front door backdrop? Pure Hallmark movie energy. It’s the kind of photo you look at and think, “Yep, she’s absolutely thriving.”
There’s something so effortlessly magnetic about this look. It’s sporty meets glam in the most understated way possible. That bodycon dress hugs her growing belly like a love letter, and the simple styling lets the bold color do all the talking.
And speaking of glow—can we talk about her hair and smile? Literal sunshine. She’s that mom-to-be who makes you want to organize your closet, do your skincare, and maybe even buy a pair of fresh white kicks.
12. Spooky & Sweet
Somewhere between a Halloween fever dream and a maternity fairytale lives this masterpiece from @km4art. Pumpkin-headed lovebirds in a golden field with striped jumpsuits and a whole lot of humor—yes, yes, and yes. If Tim Burton directed a gender reveal, this might just be the opening scene.
There’s a perfect tension here between eerie and adorable. The black-and-white stripes channel Beetlejuice chic, while the soft autumn tones soften everything up. It’s a visual wink—a reminder that pregnancy doesn’t have to be all pastel nurseries and baby showers.
This one deserves to be framed and hung up every October. It’s quirky, bold, and so full of personality. A true Halloween classic, maternity edition.
13. Avocado Toast Family Goals
Move over influencers, the real stars are here and they’re dressed as breakfast. This family from @letsdolattes absolutely nailed Halloween with a toast + avocado couple moment and two PJ Mask-wearing kiddos stealing hearts left and right.
There’s such an easygoing charm in this photo—maybe it’s the Uggs, maybe it’s the toddler power stances, or maybe it’s just a family that knows how to do themed dressing right. There’s creativity, humor, and a sense of togetherness that totally shines through.
Honestly, it’s one of those photos that makes you want to go DIY your own costume immediately (and maybe adopt a few small superheroes while you’re at it). Wholesome, witty, and full of love.
14. Mother Earth Magic
@libbyzflanagan turned her bump into a literal globe and somehow made it beautiful, whimsical, and meaningful—all at once. The blue dress, the green felt continents, and that fresh flower crown? It’s like Earth Day got invited to a maternity shoot and absolutely showed up.
This look is soft but powerful. There’s a quiet statement being made—that creation is beautiful, and motherhood is magic. It’s gentle, grounded, and kind of poetic in its simplicity.
We’re obsessed with how she let nature speak for itself here. No flashy props or gimmicks—just sunshine, blooms, and a mom-to-be looking like the goddess of growth herself.
15. Greek Goddess Realness
A moment of appreciation for @luxiegames, serving full Olympian energy in this white draped gown and pearl details. The doorway alone sets a regal tone, and she walks right into it like maternity was always meant to be this ethereal.
It’s giving Aphrodite, it’s giving Hera, it’s giving “where is her temple?” vibes. The outfit manages to be both soft and strong, and those draped pearls across her shoulder? Pure drama in the best way.
This look doesn’t just capture a baby bump—it captures legacy. There’s storytelling in her gaze, and we’re pretty sure the gods themselves are applauding from Olympus.
16. Courtside Cutie
Who needs a basketball when @madtayobray already has the MVP bump? This one’s a slam dunk for creativity—playing off the belly roundness with an actual basketball design? We see you. And we love it.
From the monochrome black outfit to the casual sandals, it’s sporty-chic with a twist of humor and a whole lot of joy. She’s glowing from the inside out, and the sunset backdrop only adds to the golden hour magic.
There’s something so real and lighthearted about this shot. Like, yes, growing a human is serious work—but that doesn’t mean you can’t have fun with it. Points scored.
17. WandaVision in the Wild
@magiccatjenny did not come to play—she came to slay in this spot-on Wanda Maximoff cosplay, complete with that iconic striped robe and red bump-friendly dress underneath. Scarlet Witch, but make it mama.
It’s part costume, part tribute, and 100% perfection. The backdrop of stars gives it that otherworldly touch, and the way she owns the look? Wanda would approve. She’s channeling all the chaos magic—just with more glow and less destruction.
This one’s a fan favorite for sure. Nerdy, nostalgic, and totally radiant. If multiverse mamas exist, she’s definitely queen of them.
18. Golden Hour Glam
First off, can we talk about the fit? This flowing lavender floral number on @mariahcarleyy is a whole vibe. It’s soft, it’s springy, and it moves with her in the kind of way that just feels right for where she’s at in her journey.
There’s something so nostalgic about this photo—maybe it’s the soft greenery in the background, or her glowing expression. Either way, it’s giving “peaceful backyard goddess” and we’re here for it.
This isn’t just an outfit—it’s a mood. A gentle ode to growth, femininity, and blooming right where you’re planted.
19. Multiverse Maternity: Wanda Edition
Round two from @mariahcarleyy and she’s back—this time literally channeling Wanda from WandaVision in what feels like a TV still. That bold stripe pattern, deep V neckline, and rich tones? We’re not worthy.
She’s got the attitude, she’s got the power pose, and she’s totally in character. It’s not just a costume—it’s a moment. Whether you’re a Marvel fan or not, you can’t deny the iconic energy here.
It’s maternity cosplay done right. Smart, stylish, and full of flair. And yes, the multiverse is clearly pregnant with possibility.
20. Tunnel of Drama
Let’s just say @naylah_b understood the assignment—and then draped it in cobwebs and glamour. This Halloween-inspired maternity shoot is part haunted house, part red carpet moment, and all kinds of striking.
The contrast of that vibrant orange dress against the spooky tunnel is chef’s kiss. Add in her confident pose and warm smile, and it’s like a goth fairytale with a happily-ever-after built right in.
This is how you do maternity with boldness. Unafraid, unapologetic, and unforgettable. She’s not just expecting—she’s expected to slay.
21. Classic Autumn Love
There’s something timeless about this shot. It’s cozy without being cliché, with burnt sienna and soft cream tones setting the mood for a fall maternity moment that feels both personal and polished. The hands making a heart shape on the bump? It’s giving Hallmark, but in the best way.
This outfit strikes the balance between comfort and put-together. The sleeveless rust dress hugs in all the right places, while the light cardigan softens the look—ideal for that golden-hour stroll or a chill backyard party. It’s an understated kind of beautiful, like love in motion.
22. Pumpkins & Parenthood
Now THIS is how you do a themed shoot. Pumpkin heads? Check. Black lace dress with a festive ribbon? Double check. There’s whimsy, mystery, and just a dash of Halloween camp. You know these two came to win the costume contest (and probably did).
What keeps it from being too gimmicky is the balance. Her dress has just the right level of drama with those sheer sleeves and V-neck, while the orange ribbon ties it all back to the season. And yes, that little pumpkin cradled in her hand? A perfect metaphor for the tiny one on the way.
23. Earth Mama Energy
If Mother Nature were to throw a maternity shoot, it would probably look like this. Ivy-wrapped toga? Check. Painted belly globe? Iconic. This costume doesn’t just show— it tells a story. And bonus points to dad as Father Time with a literal clock necklace. Genius.
There’s something beautifully theatrical here. You can tell they leaned into the idea and made it fun, but it also feels intentional. It’s not just dress-up—it’s “we’re welcoming a whole world.” This kind of creativity deserves its own photo book.
24. Skeleton Crew Cuties
Matching skeleton onesies, but make it adorable. This couple understood the assignment and turned a classic Halloween look into a pregnancy moment that’s both cheeky and sweet. The baby skeleton print on her belly? Instant serotonin.
It’s one of those effortlessly cool ideas that feels festive without any fuss. No props, no gimmicks—just soft cotton, high-contrast prints, and a whole lot of love. Bonus: these jammies could totally double as comfy loungewear post-party. Efficiency for the win.
25. Toy Box Throwback
Bo Peep and Woody got a plot twist, and it’s adorable. This couple nailed the Toy Story theme with playful costumes that are vibrant but not over-the-top. And let’s be honest—Bo Peep’s bump peeking through that pastel blue? Disney magic, but make it real life.
Their smiles do half the work, but it’s the coordinated details that seal the deal—like her crook and his sheriff badge. It’s nostalgic, yes, but also fresh and fun. The kind of look that’ll be a favorite in the baby book and on the ‘Gram.
26. Belly of Wonders
Channeling her inner Princess Jasmine, @tiffanylynnxo turned a baby bump into royalty-level glam. That burgundy two-piece is daring in the best way—soft, sheer, and fitted just enough to showcase the bump without compromising on drama.
The hair, the accessories, the bold eye makeup—it’s all working in harmony. And with the balloons and floating witches in the background, there’s a fun, enchanted energy to the whole scene. Halloween may be spooky, but this? Pure magic.
27. Gothic Reveal
Talk about mood. This dark fairytale moment is dripping in drama—from the cathedral-like backdrop to the lacey gown and crystal crown. But the real kicker? That pumpkin announcement: “Do you know what’s really scary? Twins.” Mic drop.
It’s glam, it’s gothic, it’s totally unapologetic. The makeup is bold, the lighting is theatrical, and it’s clear that @turnthepagephotographer leaned all the way into the spooky season vibes. For the mom-to-be who’s not into florals and fluff, this is the blueprint.
