25 Halloween Costumes for Pregnant Women
Dressing a bump for Halloween is one of those problems that sounds harder than it is. Most costumes are cut for a waistline you don’t currently have, and by October you may not feel like squeezing into anything stiff, scratchy, or complicated. But the bump is also the best prop you’ll ever get. It can be a pumpkin, a basketball, a disco ball, a bun in an actual oven, and nobody else at the party can pull that off.
These 25 costumes cover the whole range: funny ones that put the belly front and centre, pretty ones that just happen to fit over it, easy last-minute ideas built from clothes you already own, and a few couples’ picks if your partner wants in. Most work with a stretchy dress or leggings and a tee as the base, so you can sit, snack, and stay comfortable all night. Pick your favourite and start there.
The Lorax With a Bump
A round orange belly is most of what makes the Lorax recognizable, so a bump does half the costume for you. The rest is a fitted orange bodysuit with a hood, a big yellow mustache, and matching yellow eyebrows. A small potted truffula tree held up in one hand finishes it.
This is best for someone in the second or third trimester, when the bump is big enough to look like the character’s whole body. It also needs a partner or friend willing to play the Once-ler, since the Lorax is funnier standing next to the person he’s scolding. A wide-brim hat, a fuzzy red scarf, a vest, and green gloves are all that person needs.
If you’re early on and not showing yet, pick a different idea from the list, because a flat front on an orange suit just looks like an orange suit. I’d also pass if you run hot or will be outside for hours. The stretch fabric covers you from head to wrists to ankles, and a one-piece is a hassle every time you need the bathroom.
Cow Belly Costume
A cow costume works best when the belly add-on looks light and sits low. The usual problem is a udder that sticks too far out or lands too high, which makes it look awkward when you walk or sit. I’d use a soft pink piece with small stuffed teats and pin it under the bump, not across the front of it.
A plain white base helps, but thin fabric can turn see-through under bathroom or party lights. Go with thicker knit and check it in bright light first.
Matching Jack-o’-Lantern Faces
The face belongs right on the curve of the bump, with the eyes just above the widest point and the grin wrapping a little around it. Set any higher, on the chest, it becomes an orange jumpsuit with a face on it, and the bump stops mattering.
Black fabric shapes on a rust jumpsuit are all it takes. A partner in a rust sweater with the same face makes it a pair, and both of you cupping your hands under the grin ties the photo together.
Oven and chef costume
A soft oven front leaves room for the bump instead of boxing it in. Make the oven as a flat panel from white felt, quilted cotton, or thin foam covered in fabric, then cut a clear vinyl window over the belly. The window is the part that sells it, because the bump becomes the bun without needing extra pieces.
A fabric version changes how the costume sits. Cardboard can crease at the waist and stick out when you walk, while felt or foam hangs closer to the body. Add silver circles for the knobs and a strip of shiny tape for the handle. If you want the oven to look more like stainless steel, use silver fabric instead of white. That makes the costume look more like a real appliance, but the belly window may need a darker outline so it does not disappear.
For a partner costume, a chef hat and apron are enough. The apron can say “The Bun Maker” if you want the joke spelled out.
Fairy Godparent Couple
Two people with crowns, wings and star wands, each with a different hair color, are all this costume needs. Everything else is clothes you probably own. For the pregnant partner, that means a white button-up, a black skirt that sits below the bump, and a long black tie.
Do the hair first, because it matters more than anything else on the list. Bright green on the ends of dark hair, and a pink-red on the other person, tell people who is who from across the room. Hair color takes the longest to get right and can’t be fixed once the wings are on, so finish it before you put on any other piece.
After that, dress in this order: shirt, tie, skirt, wings, crown. Leave the shirt open over the belly and let the tie hang straight down the middle, where it points at the bump. Clip the crowns to the hair so they stay put when you turn your head. The wands go last, and a pair of thin ones with gold stars is plenty.
Winnie the Pooh
That round belly works well for Winnie the Pooh, especially for a house party or a family Halloween night where people will get it right away. The red top and yellow skirt put the color idea across fast, and a small honey pot gives you one prop to carry without much fuss. I’d use this for an indoor setup over a long night, since it is built from light clothes and plain sneakers.
Near the snack table is the best spot for it. The honey pot lands better there, and the costume still makes sense when you are standing around talking or sitting for a bit. If you want to go out in cold weather, I’d add a yellow cardigan or tights.
Hole in One Belly
The belly becomes the putting green, and the baby is the “one.” A round patch of dark green body paint covers the bump, with a small red flag on a stick, a white golf ball, and the words “hole in” painted across the top. Water-activated face and body paint is what you want for this, since it goes on in thin layers and washes off with soap. A large flat brush covers the circle faster than a sponge.
If you’d rather not paint skin, cut a circle of green felt and stitch or glue it to a fitted tank, then add the flag and ball in felt too. The rest of the outfit is a green two-piece with a cropped top that ties above the bump, but green leggings with any short top would work just as well.
Your partner needs a polo, khaki shorts, a cap, and one club. I’d paint the lettering in white or yellow, because dark letters on dark green get lost in photos.
Disco Ball Belly
With a silver sequin panel centered over the bump, the dress becomes a disco ball costume without needing much else. A gray strapless dress works well because it lets the shine sit on the belly instead of fighting with a busy print. The slit also keeps the long dress from feeling too heavy.
I would focus on the material more than the dress shape. Flat silver sequins give the belly a softer shine, while small mirror tiles make it look more like a real disco ball. Mirror tiles catch more light, but they need a flexible base so they can move with you. Gold sequins change the costume into more of a disco queen look, especially with a tan jacket or wide-collar shirt on a partner. Keep the shiny section wide enough to cover the front of the bump, then let the dress stay plain around it.
Cropped Graphic Tee and Ears
A cropped graphic tee and a pair of Halloween ears make a costume you can wear through a long day outdoors, so it works best for a theme park trip or a fall festival. The orange tee carries a dragon print, which stands in for a character without any face paint. A pumpkin toy in one hand finishes it.
Black cargo pants sit low under the bump and have pockets for a phone and snacks. I’d buy the tee one size up so the hem stays put while you walk.
Winnie the Pooh trio
The yellow belly panel is what makes this one land. Build the costume around that first, then add the rest: a red top with “Pooh,” yellow bottoms that cover the bump, and yellow bear ears. On your partner, put a yellow shirt with “HUNNY” in dark letters and a yellow beanie, then bring in the dog with a bee costume if you want the full group.
Lettering placement matters most. Put “Pooh” high on the chest so the bump stays clear and bright, and let the yellow skirt or shorts carry the round shape. I’d also keep the red shirt a bit lower than this, since it can ride up.
Juno and Paulie Bleeker
A bump under a red-and-white striped tee gets you halfway to Juno. The rest comes from a gallon jug of orange drink held at the hip. That jug matters more than any piece of clothing. Without it, a camo hoodie, striped shirt, jeans and maroon sneakers look like a regular fall outfit, and people will guess “pregnant” long before they guess the movie. Once the orange label sits right against the belly, the costume is easy to recognize from across a yard. I’d carry it by the handle, low and a little forward, so it stays next to the bump in every photo.
A partner can put Bleeker together in an afternoon. He needs a maroon tee with a gold crest, shiny gold running shorts, a yellow headband and wristband, and striped tube socks pulled up to the knee. Make the shorts as short as he’ll tolerate, because they carry his half of the joke.
Skeleton Baby Bump
Use a black long-sleeve dress as the base, then add white bone shapes across the chest, arms, legs, and belly. The bump is the main part: place a small curled baby skeleton on it so it sits where the belly rounds out. White iron-on vinyl gives the cleanest edge, but felt, fabric paint, or freezer-paper stencils work if that is what you have.
A dress with stretch helps the ribs and little bones stay in place as the fabric moves. If you are making this fast, buy a plain skeleton dress and add the baby bones over the stomach with peel-and-stick felt or hand stitches.
Violet Beauregarde, Blueberry Stage
Violet turning into a blueberry is the joke, and it only works once there’s a bump to go with the blue. A zip-up tracksuit in one bright shade, a blonde bob wig and a pink bubble of gum make up the outfit. The tracksuit is loose and stretches, so it fits a third-trimester belly without any alterations.
This is right for anyone who wants to stand around at a party in comfortable clothes and still get the reference. It’s better still if your partner will wear a purple velvet coat and an orange top hat, since Violet makes the most sense next to Wonka. A toddler can join in too, holding a cardboard chocolate bar in front of them.
Pick something else if you’re early on and not showing yet, because the blueberry punchline needs a visible bump. Pass as well if you dislike wigs or face makeup, since the purple tint on the nose is part of the look. And if the party is somewhere warm, a polyester tracksuit gets hot fast.
Ladybug and bugs
A ladybug belly works well when the bump is the body, but the shape can get muddy fast once you add wings, spots, antennae, and extra bugs around it. The cleanest version starts with one clear red oval across the front and evenly spaced black dots. If the spots drift onto the sides, the bump looks wider instead of rounder, and the ladybug shape gets lost.
Wings are usually the next problem. Big wire wings look good standing still, then catch on door frames, car seats, and small kids. A soft pair that sits close to the back is easier to wear for more than ten minutes. I would also keep the antennae short. Tall curled ones tip forward and start to feel heavy by the end of the night.
If you want to turn it into a group costume, limit the rest of the family to one bug each. A green grasshopper and a child in black with large eyes are easy to read. Once everyone has wings and extra props, the pregnant ladybug stops being the main idea.
Moon Bump and Astronaut
A round belly painted as the full moon gives the partner an easy role. He goes as the astronaut, in a white jumpsuit with a few mission patches and a toy rocket in one hand. The black glitter top and sequined pants act as the night sky, so the pale gray bump stands out from across a room.
Painting the bump as Earth instead changes the costume more than you’d expect. Blue oceans and green land show up better in dim party light than soft grays do, and the astronaut now looks far from home rather than about to land. Earth takes more paint and a steadier hand around the coastlines. The moon only needs white, two grays and some sponged craters.
Willy Wonka And Violet
The bump is the blueberry, so this costume works best when the clothes frame it instead of hiding it. Use a blue velour tracksuit, a blonde bob wig, and blue or purple fabric over the belly. Stretch mesh, a thin tank, or body paint can cover the bump if the jacket sits open.
For Wonka, build the outfit from a long red coat, dark shirt, black pants, a top hat, white oval sunglasses, purple gloves, and a cane. A red cardigan or robe can stand in for the coat if that is what you have. For Violet, a blue hoodie and sweatpants are enough if the fabric is shiny or close in color. Add pink blush high on the cheeks to push the candy-factory look without adding much else.
Red Dress and White Bonnet
A handmaid costume comes down to a red dress and a white bonnet, and the bonnet is where most people run into trouble. A sheet of paper or thin card folded into wings flops forward after a few minutes and ends up covering your eyes. I’d use stiff card, cut the wings shorter than seems right, and sew or pin them to a plain white cap so they hold their angle.
The dress is easier. Pick a true red with some weight to it, and a cut that gathers under the bust so the buttons down the front don’t pull across the bump.
Thing 1 and Thing 2
A Cat in the Hat couple setup works best if you want the bump to be part of the joke, not something you have to hide. Put “Thing 1” on one shirt, then use the belly for “Thing 3” and “Thing 4” on a red dress. That placement matters. The extra circles turn the bump into the center of the costume instead of an add-on.
This one is good for people who want very little prep and do not want to carry props all night. A fitted knit dress keeps the numbers easy to read, and a small blue headpiece is enough to point to the theme. It also helps if your partner is willing to match exactly.
Pick a different idea if you do not like body-hugging clothes or you want something less direct. I’d also space the lower badges a bit more if the dress pulls across the stomach.
Avocado and Toast Couples Costume
The bump becomes the avocado pit, and your partner goes as the toast. Both pieces are flat cardboard, so they’re cheap to make and easy to put on over regular clothes.
Start by holding a large sheet of cardboard against your body and marking two spots: the center of your bump and your face. Cut a round opening at each mark, then draw the pear shape around them. The pit needs to sit right on the bump, so measure for it before you draw anything else. Paint the flesh bright green with a darker rim. The toast is plain cardboard with brown painted crust along the edges.
Handmaid Costume
The white winged bonnet is the piece that makes this land. Without that high, rounded shape framing the face, the red dress would look like a plain maternity dress, even with the belly centered under the fabric. Use a knee-length red dress with sleeves, then put most of your effort into the bonnet so it holds its curve and sits low enough at the sides. A black suit and tie beside it makes the reference clearer.
Painted Jack-o’-Lantern Belly
A belly painted orange with a carved-pumpkin face is the easiest costume on the list to pull together, because it only asks you to wear what you already own. Black leggings and a fitted black top leave the bare belly as the one bright thing, and a jacket left open keeps the paint in view.
This one works best for a front porch photo or a small get-together at home, where the paint doesn’t have to survive a crowded party. A porch already set up for fall helps a lot. Gourds on milk cans, a lantern by the door and a wooden scarecrow all sit in the same orange, green and brown as the paint, so the belly looks like part of the display.
The costume also makes a good announcement for the final weeks. A small letter board held at the side lets you add a due-date line, and I’d keep the wording short enough to read from a few feet away. Paint on the day you shoot, since it will smudge once you sit down.
Golf ball and golfer
A golf ball costume works well for a bump because the shape is already right. Start with a black dress or long top and leggings, then pin or glue a large white circle over the belly. Foam board, felt, or poster board all work for the ball, and you can press in dimples or draw them on.
Next to it, the golfer only needs plaid bottoms, a collared shirt, a sweater vest, and a cap. White gloves and golf shoes help, and any club will get the point across.
Mike Wazowski Tee Dress
A lime green tee with one big eye and a toothy grin printed on the front makes a bump into Mike’s round body, no sewing needed. Worn a few sizes up, it hangs like a short dress.
I’d buy it closer to your usual size instead. The cotton stretches over the belly, the eye lands right on the curve, and the face looks round rather than baggy. A blue ball cap finishes it.
Eight Ball Bump
An eight ball costume works because the number sits right on the roundest part of the belly. Start with a black dress or black top and skirt, then add a white felt or paper circle over the bump with a black 8 in the center. That one flat circle matters more than the rest of the outfit. Without it, the look is just black clothes, and even a pool cue next to you will not make the idea clear enough.
The circle should be large enough to cover most of the belly from the front, not a small badge pinned off to one side. I would attach it with fabric tape, safety pins from the inside, or a loose sash if you do not want to stick anything to the dress. A second person can wear all black and carry a cue, but the belly label is the part people need to see first.
Belly as Mike Wazowski
A round green belly with one big eye and a wide toothy grin is most of Mike Wazowski already, so the rest can stay plain: a black top, black leggings and a cap with MU on it.
Wear it after dark, for trick-or-treating, a neighborhood party or a porch with a candy bowl. Black clothes fade in low light, so the green belly is all anyone sees.
Road crew bump
A road crew costume lands fast when the bump becomes the caution sign. Paint or tape “BUMP” on a yellow diamond for the belly, then use the same orange safety vest on everyone else so the group reads together.
Scale is what usually goes wrong. If the belly sign is too small, the joke gets lost under the vest or black clothes. If it is too big, it curls at the sides and sits oddly when you move. I’d keep it wide enough to read from a few steps back, but small enough to stay flat on the front of the bump. A stiff foam board shape or light cardboard works better than thin paper.
The other miss is piling on too many props. One road sign and a pair of cones are enough. Hard hats and clear glasses help, but heavy boots, tools, and extra signs can start to feel like costume parts instead of regular work gear.
Blueberry Violet and Oompa Loompa
Violet, the girl who swells into a blueberry, works best in the third trimester, when the round belly is the joke. A fitted blue jumpsuit in a ribbed knit stretches over the bump and stays comfortable through a long night of handing out candy. A blonde bob wig and a little blue makeup on the nose finish it.
This one needs a partner willing to wear a green wig, white overalls and striped bands around his calves, so it fits couples who both like dressing up. If you’d rather go solo or you’re early on and barely showing, pick another idea from the list. A blue bodysuit over a small bump just looks like a blue bodysuit.
