The baby decides which costume works, since a fussy newborn ends the photo session no matter how good the rest looks.
The ideas run from skeleton pajamas that double as real sleepwear to a Jurassic Park set made with poster board signs, and most of the parent outfits can come from clothes already in your closet.
1. Addams Family
Black clothing you already own does most of the work here. Gothic Addams dressing is mostly a matter of dark layers, so a closet raid covers the parents and the older girl.
The newborn is the easy one. A plain dark onesie keeps the baby comfortable, and skipping stiff costume pieces means fewer fussy moments mid-photo.
A white brick wall or a plain background makes dark outfits stand out, so pick your spot before the baby gets hungry.
2. Star Wars
Star Wars gives each family member a different character, which is why it works for a group this size. Chewbacca, a Stormtrooper, Darth Vader and a BB-8 outfit can be split between parents and kids without anyone matching.
BB-8 is my pick for the baby. A round, soft outfit suits a small body better than armor or a mask would.
Save the helmets for the adults. Anything covering a baby’s face is a bad idea.
3. Wizard of Oz
A scarecrow hat, a blue gingham dress and a baby lion cover three of Oz’s best-known characters with very little effort.
Mom as the Scarecrow, the toddler as Dorothy and the newborn as the Lion is a split that makes sense for most households.
Gingham dresses are easy to find secondhand, which keeps the cost down.
A lion outfit with a hood is the sort of thing a baby can nap in, so choose a soft one. Pumpkins on the porch make a fine fall backdrop.
4. Jurassic Park
A wagon is the smartest prop for a family costume with a newborn, since it holds the baby, hides the diaper bag, and saves your arms.
It holds the babies, hauls the gear and becomes the set, with homemade "DANGER 10,000 VOLTS" and "JURASSIC PARK" signs taped on.
Parents in safari outfits keep the adult side simple, and the dinosaur costumes go to the little ones. Three babies in one wagon is a lot of cute, though it works just as well with one.
Make the signs from poster board and you’ve spent almost nothing.
5. Baby Shark
Here the joke carries the costume: a lifeguard shirt on Mom, a blood-stained shirt on Dad, and a white shark outfit on the baby. Nobody needs to buy much beyond the shark.
I like it because the parent outfits are ordinary shirts you can wear again. The red "LIFEGUARD" shirt does the heavy lifting.
Any shirt can become the bloody one with some red fabric paint, so test it on an old tee first. Dad’s the one who’ll want to wash it right away.
6. Alice in Wonderland
Alice in Wonderland suits a bigger family because the story has so many roles to hand out. Two adults, two kids and a newborn can each take a different character without much overlap.
Pick the baby’s outfit first, since that’s the least flexible piece. A soft one-piece beats anything with layers or stiff tulle.
Apples on the ground add a story touch for free if you shoot in a wooded spot. Keep the shoot short, because newborns tire quickly outdoors.
7. Where the Wild Things Are Costume
A wagon dressed up as Max’s boat is the clever part of this costume. The toddler rides in it, so nobody has to carry a kid who gets tired of walking.
Label the side of the box "MAX" in big letters so the costume reads at a glance, even from across the yard. Poster board and a marker will do it.
The baby can wear a creature outfit, which leaves the parents free to be creatures too.
8. The Little Mermaid
The Little Mermaid has enough characters to put a big family in costume without anyone doubling up. Dad makes a fine King Triton, and a baby in a fish outfit is the easiest role to fill.
Soft and simple beats anything with scales that scratch.
With a group this big, shoot outside in daylight and keep it quick. Someone will lose patience fast.
9. Skeleton Pajamas for the Entire Family
Matching skeleton pajamas are the lowest-effort costume on this list. Everyone, baby included, wears the same black print, and the dog can join in with a skeleton shirt.
I like that the pieces double as real pajamas, so they get worn again after Halloween. That makes the price easier to justify.
Pumpkins by the front door make a backdrop all on their own, so props can stay in the closet.
Check that the baby’s pair is soft and made of stretchy fabric, since stiff or scratchy sleepwear is no fun to dress a newborn in.
10. The Flintstones
Fred, Wilma and Pebbles fit a family of three perfectly, and a leopard print outfit on the baby is the piece that sells it. Pebbles does most of the work here.
Wilma’s look is simple enough to put together from clothes you may own, so spend your money on the baby’s outfit.
An indoor hallway or staircase works as the setting. No travel is needed, which helps when the newborn is due for a feeding.
11. Harry Potter
A newborn in a Harry Potter outfit is the best excuse to dress the whole house in robes. In a big group, every kid gets a role, and the baby gets the cutest one.
Robes layer well over everyday clothes, so older kids stay warm outdoors. Keep the baby’s layers light and soft, though.
Fallen leaves make a good backdrop, and a wooded spot costs nothing. Group shots with several kids take patience, so take the baby’s pictures first.
12. Barbie Family Costume
Cardboard doll boxes are what turn neon workout clothes into a Barbie and Ken costume. Make the boxes labeled "Barbie," "Ken" and "Mattel" from cardboard, and everyone stands inside for the photo.
The clothes are bright athletic pieces you may already own, so the box is the only real project. Cut a front panel and add a window if you want to be fancy.
A baby can’t stand in a box, so hold the newborn or place the baby in one on a flat surface.
13. Toy Story
Woody, Jessie, Buzz and Rex give each person in a small family their own character, so nobody has to double up. Rex is the natural pick for the baby, since a dinosaur outfit is usually one soft, roomy piece.
Cowboy hats and boots for the adults are easy to borrow or find secondhand. Keep the baby’s costume free of stiff parts so the newborn stays comfortable through the shoot.
A plain door makes a clean backdrop, so no props are needed.
14. The Nightmare Before Christmas
Dark, striped and spooky pieces make this one stand out, and a bright balloon arch behind the family adds contrast that a plain wall can’t. The mix of moody costumes and a colorful setting is what I’d copy.
Give the newborn the simplest outfit in the group.
Shoot indoors and the whole thing stays warm and quick, which matters with a baby.
15. The Sandlot
Baseball clothes make The Sandlot an easy family costume, since jerseys, caps and jeans are things many closets already hold. A chalkboard sign with the movie title and a quote tells everyone what you are.
A home plate on the grass is a cheap prop that anchors the photo.
Dress the newborn in a soft baseball-style outfit and place the baby on a blanket. Take that picture first, before the older kids get restless.
16. The Lion King Family Costume
A mom and baby in matching brown lion outfits is the simplest Lion King idea on the list. Two costumes, one photo, and no coordination across a big group.
Choose a soft, hooded baby version and skip anything scratchy. The baby will wear it longer than the shoot.
An indoor wall by a window gives you natural light without going outside. Dad has 2 easy options: wear a lion costume of his own, or stay behind the camera and take the photos.
17. Superhero Family Costume
Superhero costumes let each person pick a different hero, so one family can be Captain America, Spider-Woman, Spider-Man and a baby Hulk. Mix and match without worrying about a shared theme.
The baby Hulk is my favorite piece. A soft green one-piece works better on a newborn than a padded suit with a mask.
Masks are fine on the toddler for a quick photo, but keep the baby’s face uncovered.
A white fence and a front yard make a clean backdrop, and it costs nothing.
18. Farmers and Farm Animals
Cowboy hats on the parents and plush animal outfits on the babies make this one easy to pull off. A cow and a chicken suit twins or two close-in-age babies well.
Parents can wear plaid shirts, jeans and boots they already own, so the only purchases are the animal costumes. Choose plush ones that are soft and snug.
A grassy field makes the setting. Hold each baby close, and keep the shoot short.
19. Peter Pan and Neverland Fairies
Peter Pan sorts a family into easy roles: a green-hatted Peter, a pirate, and fairies with wings. A baby boy and a toddler girl can take whichever fits their size.
Wings on a newborn are the piece I’d skip or keep tiny, since anything stiff on the back is awkward when a baby lies down. Put the wings on the toddler instead.
A plain wooden wall keeps the focus on the green and the pirate gear.
20. Spider and Insect Pair
A spiderweb outfit on Mom with a plush spider attached, paired with a baby in a bug costume, needs no group planning at all. Mom is the spider, the baby is the catch.
Pick a soft, one-piece bug outfit for the baby and keep the plush spider on your own clothes, away from the baby’s face.
It works at a cider stand or any autumn outing, since you can wear it while you walk around.
21. Winnie the Pooh and Friends
The newborn takes the Pooh costume, which leaves Tigger and Piglet for the parents to split. Pooh is the right role for a baby because the round, soft shape is already what the character looks like.
Dad and Mom can split Tigger and Piglet however the outfits fit best.
A plain wall is all the backdrop you need. Take the baby’s shots first, while the newborn is calm.
22. Monsters, Inc. Family
Monsters, Inc. fits a big household because the characters are furry suits that hide ordinary clothes: Sulley, Randall, Mike Wazowski and a yellow monster all appear in one living room shot.
Give the baby the softest suit, and hold the newborn rather than standing the baby up. Sulley’s big fur suits an adult best.
Shooting indoors keeps things warm and quick. A living room works fine, so there is no need to travel.
23. Frozen Family Costume
Olaf is the role for the newborn: Kristoff and Anna for the parents, Elsa for the older girl. Every character gets its own person, so nobody doubles up.
Choose a soft Olaf outfit without stiff arms or a hard head piece. A snowman shape is round and forgiving on a small body.
Woods make a pretty setting, but keep the shoot short so the baby doesn’t get tired outdoors.
24. Beekeepers and Baby Bee
Parents in white beekeeper suits holding a baby dressed as a bee makes a sweet reversal: the keepers end up cradling the bee. A stroller decorated as a honey pot adds the finishing touch.
The stroller does double duty, so you carry nothing extra. Decorate it with paper or fabric and keep the baby’s bee outfit soft.
Hats with veils can block your view, so check you can see the baby before you pose.
25. Sushi Chef and Nigiri
A soy sauce bottle is the funniest role in this costume, and a black dress with a label across the front is all it takes. Dad’s sushi chef outfit finishes the table, and the baby is the nigiri.
Choose a soft nigiri outfit that fits snugly, nothing stiff or bulky. Hold the baby between you so the pieces read as one meal.
Print the "SOY SAUCE" label big and clear. Plain paper stuck on the dress works fine.
26. Bakers and Cupcake Baby
Chef hats and aprons turn 2 parents into bakers, and the baby becomes the thing they made. A pink cupcake outfit is the whole punchline.
Aprons are cheap, and white hats are easy to find, so spend on the baby’s costume.
For a cupcake baby, pick a soft, loose outfit over one with a stiff, structured frosting hat, since newborns sleep through most of the day.
Keep the hats secure when you lean in with the baby. A living room with good light is all the setting this needs.
27. Moana Family Costume
Maui holding a newborn next to Te Fiti makes Moana a good fit for a family with an older girl. Each person gets a clear role, and the baby is simply the one being held.
Maui’s look is the most work, so decide who wears it before anything else. Keep the baby’s outfit soft and simple, with no pieces that press on the back or neck.
Shoot against a bare wall inside, and the costumes get all the attention while the room stays cozy for the baby.
28. Ice Ice Baby Costume
Ice, ice, baby is a pun you can wear: white shirts with "ICE" overlays on the parents, and a baby in sunglasses and a headband. Nobody has to buy a full costume.
Make the overlays from paper or fabric and attach them to plain white shirts you already own. That’s the cheapest idea on this stretch of the list.
Sunglasses on a newborn are for the photo only. Pop them on, snap fast, and take them off.
Tips for Choosing Costumes
The baby is the least flexible piece, and a fussy newborn ends the photo session no matter how good the rest looks.
Soft, breathable fabric that won’t irritate skin comes first. Check that nothing is tight or restrictive, because a costume that pinches makes for a short, unhappy evening.
For long nights out, babywearing or matching pajamas tend to work best. A carrier keeps the baby close and saves your arms, and pajamas are comfortable for hours.
A spare layer goes in the diaper bag for me, since a night out in October can turn chilly fast.
DIY Costume Ideas
Start in your own closet, because plain bodysuits and everyday clothes cover more costumes than you’d guess. A low-buy approach keeps the focus on fun instead of getting every detail perfect.
Another option is a laundry pile. Black tees and leggings work as a base for a laundry-day group; pin on odd socks, dryer sheets and small towels, and the baby becomes one lost sock.
Ghosts and tourists need almost nothing.
For ghosts, cut eye holes in sheets for the older kids and adults. Tourists take almost no shopping: Hawaiian shirts, sandals worn with socks, sunhats and sunglasses are already in most closets.
A baby who hates scratchy fabric or crowds should wear whatever feels best, and the costume can bend around that.
Halloween is the perfect excuse for families to get creative together, no matter their size. Whether you’re a pair, a trio, or a whole crew of six or more, this collection of family costume ideas has something for everyone.
Safety Considerations
Check every costume for small parts before the baby wears it. Loose strings, small buttons and little decorative accents can all become choking hazards, so cut them off or pick a different piece.
Look at the neckline and elastic too. Tight necklines and snug elastic are uncomfortable, and a costume that restricts movement is not worth the photo.
Leave off any mask or hat that covers the eyes, nose or mouth, because a baby can’t push it away. Many babies also find hats and headbands annoying, which leads to tears, so keep accessories to a minimum.
Stick to soft, breathable fabric and keep the whole outfit simple.
Frequently Asked Questions
What are some easy DIY costume ideas for families?
Start in your own closet. Most of these costumes start with things already in your drawers: plain bodysuits, black tees, leggings, a loud Hawaiian shirt, a sunhat.
How do I make sure Halloween costumes are safe for babies?
Check for small parts before the baby wears anything, including loose strings and small buttons, which are choking hazards. Pick soft, breathable fabric for the baby, and check that no seam, snap or elastic pinches or squeezes.
Skip masks, hoods that slide down and helmets so the face stays clear, and toss a spare layer in the diaper bag, since October nights drop in temperature quickly.
What are some popular family Halloween costume themes?
Movie and character themes are the easiest to build around a newborn.
Star Wars, Toy Story, Frozen and Winnie the Pooh give each person a separate role, and a soft, round outfit like BB-8, Rex, Olaf or Pooh suits the baby.
Pun and food themes like Baby Shark, sushi or bakers with a cupcake baby work well too.
If you want the least work, go with matching skeleton pajamas; the whole family can wear them to bed long after Halloween is over.
