Monkeys are one of the easiest animals to dress a baby as, because the character lives almost entirely in a hood, two round ears and a lighter belly. Once that base exists, a red shirt, a vest or a tiny crown turns it into something new. I build every version here on a soft romper or jumpsuit that opens for diaper changes, with breathable fabric, no tight elastic and nothing detachable within reach of curious fingers. The face is stitched onto the hood, so the baby's own skin never needs makeup. Below are thirty takes, from a plain brown monkey to costumes that rope in the stroller, the carrier or the whole family.
Sewing the Monkey Base Once and Restyling It
If you can sew a little, the most useful thing you can make is one good monkey base that every variation below sits on. I build it in four parts, and each one has a detail that decides whether it survives a whole evening.
- The hood. Cut it from the same brown fleece or cotton as the romper and line it with jersey so it's soft against the head. Make the opening generous; a tight hood pushes on the cheeks and gets pulled off.
- The ears. Two circles of brown with smaller tan circles on top, lightly stuffed and sewn into the hood seam rather than onto the surface. Ears stitched only on top flop forward by the end of the night.
- The belly. A tan oval topstitched close to the edge. Felt or fleece needs no hemming, which keeps the panel flat for tummy time.
- The tail. A narrow tube filled with a little fibrefill, no wire, stitched to the romper high on the back. Short tails stay out of the diaper zone and don't snag on stroller wheels.
With that base made, the rest of the list becomes add-ons: a vest, a cape panel, a stitched-on hat shape. I attach most of them with hook-and-loop so the romper goes through the wash on its own and comes out as plain pyjamas for the rest of the winter.
1. Classic Brown Baby Monkey Costume
The plain brown monkey is the one I'd sew first, since every other look on this list starts from it. A brown footed romper with snaps or a two-way zip, a tan fleece oval on the tummy and a hood with padded round ears do nearly everything. A little felt tuft on top and an embroidered smile around the hood opening give it a face. Stitch the short tail high on the back, above the diaper area, so it doesn't get soaked or sat on. Nonslip brown booties play the feet, and a plush banana can sit nearby for photos, held by an adult if the baby is very small.
2. Gray Baby Monkey Costume
Charcoal, silver and cream make a quieter monkey that photographs well against autumn leaves. I'd build it on a lightweight gray fleece jumpsuit with an ivory belly panel. The hood gets large gray ears with pale centres and embroidered eyebrows, plus a small tuft of dark faux fur stitched down firmly. Faux fur sheds at the cut edge, so I trim the pile short around the seam allowance before sewing. Mitt-style cuffs should stop at the wrist and leave the fingers free. A curled fabric tail and a plush banana beside the baby finish it.
3. Sock Monkey Baby Costume
Red, cream and heather gray are the sock monkey's whole identity, so that palette has to be right. Look for a knit or jersey one-piece in gray marl with a cream belly and red cuffs. The cap carries padded ears, a cream muzzle panel and a red pom-pom stitched on with several passes of thread. Embroider the eyes and mouth rather than using safety eyes. Knits are the risk here: some itch around the neck and wrists, so I rub the fabric against my own inner wrist before choosing it. Gray booties with red soles and cream toes match the classic toy.
4. Baby Monkey Costume With Banana
A banana says monkey faster than anything else. Over a chocolate-brown cotton romper, add a caramel belly, rounded ears and soft foot covers. The hood carries embroidered nostrils and a smile. I make the tail from fabric and stuffing only, never wire, because wire works its way through the end of the fabric after a few bends. A bright plush banana rattle is the prop, and I check its seams with a firm pull before handing it over. A removable yellow bow tie or a felt banana patch on the chest ties the colour together for a parent-and-baby photo.
5. Curious Monkey Baby Costume
For a Curious George-inspired look, the single red shirt does all the identifying. Dress the baby in a brown hooded romper with a tan belly, round ears, a soft tail and brown booties. A lightweight red T-shirt layered over the top should be one size up so it doesn't bunch at the neck or block the snaps. An embroidered face and a small brown tuft on the hood replace any wig. Hand an adult the yellow plush banana. If a parent wears yellow and a wide-brim hat, people will name the costume before you reach them.
6. Flying Baby Monkey Costume
The flying monkey is a storybook favourite, and the wings are where homemade versions go wrong. Rigid wings make sitting and carrying awkward, so I cut flat padded wing shapes and stitch them across the back. Start with a gray fleece romper, ivory belly, attached tail and matching booties. A short blue vest with red felt shapes sewn on goes over the top, and a tiny blue cap is stitched straight onto the hood so there's nothing to lose. It makes the most sense as part of a Wizard of Oz family costume, with adults as the other travellers.
7. Jungle Baby Monkey Costume
Green felt leaves turn a regular brown monkey into a jungle one with very little effort. Felt is a good choice because it doesn't fray, so the leaf edges can stay raw and still look neat after a wash. The base is a brown cotton jumpsuit with a beige belly, soft ears, an embroidered hood and footed bottoms. The leafy vest goes on top, with flat leaves sewn around its edges. A bright botanical backdrop in the photo does more for the theme than loose decorations in the stroller ever will.
8. Circus Baby Monkey Costume
Brown velour reads as vintage circus straight away, especially with a red vest trimmed in flat gold ribbon. Add a cream belly and a monkey-ear hood, a small blue bow tie stitched firmly at the neckline and a tiny red cap sewn onto the hood. Babies pull at anything that jingles or glints, so I leave bells, sequins and dangling buttons off entirely. A light plush drum beside the baby gives the circus idea a prop that's safe to grab.
9. Ballerina Baby Monkey Costume
Soft tulle matters on the ballerina. Stiff netting scratches thighs and stands out awkwardly when a baby sits, so I use a few layers of soft tulle instead. The base is a pale brown or blush footed bodysuit with a cream belly and a matching hood with round ears and embroidered features. A satin bow stitched near one ear echoes the skirt. Pink booties with painted or printed ballet-slipper lines suggest the shoes, and I never add ankle ribbons. A plush banana wearing its own pink bow is the joke that makes people smile.
10. Superhero Baby Monkey Costume
The superhero monkey gets its look from a bright blue chest panel with a banana emblem sewn flat in the middle. Under it goes the usual brown jumpsuit with a tan belly, tail, padded ears and nonslip booties. The cape is the part I'd treat carefully. Keep it short, above the waist, fastened at the shoulders with hook-and-loop rather than a tie at the neck, and take it off before naps, crawling time and the car seat. Red boot covers make the feet heroic without a mask.
11. Astronaut Baby Monkey Costume
An astronaut monkey flips the usual colours: a white sleeper or jumpsuit becomes the base, with a silver belly panel and brown monkey ears on the hood. Silver fabric tends to be stiff, so I use it only for the belly and keep the rest cotton. Flat patches shaped like stars, planets and bananas decorate the chest and sleeves. The "space pack" is a thin padded panel sewn to the back, never a separate backpack with straps. Short brown cuffs at the wrists remind everyone it's still a monkey, and a plush moon nearby completes the scene.
12. Chef Baby Monkey Costume
The chef monkey layers a white cotton bib-style jacket over a brown footed romper with a tan belly, ears, tail and booties. Fabric-covered buttons look the part, but they must be sewn through the jacket several times so a baby can't twist them loose. A small chef-hat shape stitched to the monkey hood is far better than a loose hat, which comes off in seconds. Embroidered eyes and a smiling muzzle make the face. An adult holds the plush banana or toy spoon, and it fits easily into a food-themed family group.
13. Pirate Baby Monkey Costume
A pirate monkey can feel adventurous with no sword in sight. Start with the brown monkey romper and add a red-and-white striped cotton vest, plus black footed pants or dark booties. I never tie a scarf around a baby's neck, so the red bandana is a small panel stitched straight onto the hood. A black felt patch with a banana emblem can sit on the chest, but the eyes stay uncovered. Keep any treasure pouch stitched to the back, well out of reach, and the family pirate crew can do the rest.
14. Farmer Baby Monkey Costume
Overalls are a smart base for a farmer monkey, provided they fasten with snaps rather than heavy metal hardware, which pinches and gets cold. Over a brown bodysuit and leggings, add the soft overalls, a tan belly patch, a short tail and a brown hood with padded ears. A gingham patch or embroidered banana dresses up the bib. A lightweight fabric hat shape sewn onto the hood replaces real straw, which scratches. Brown crib shoes look like tiny work boots, and any apple or basket stays in a parent's hands.
15. Bookworm Baby Monkey Costume
The bookworm monkey suits a library story hour or a quiet first Halloween at home. It's a soft brown romper with a cream belly, a hood with round ears and embroidered features, and a small felt tuft. A green cardigan-style vest goes on top, with a flat fabric bow tie at the neck and a tiny fabric book patch on the front. I leave off toy glasses, which slide down a baby's nose and get flung. A real board book beside the baby is the prop that makes sense.
16. Pumpkin Patch Baby Monkey Costume
Orange accents shift the monkey into fall. Build it on chocolate-brown fleece with a caramel belly, round-eared hood, tail and booties, then add an orange vest or a short tulle collar with flat green leaves. A little fabric pumpkin stitched beside one ear replaces a separate headband. For pumpkin-patch photos, I lay a clean blanket down and keep the baby off loose hay, which is scratchy and dusty. A plush banana with an orange bow keeps the joke going.
17. Rainbow Baby Monkey Costume
Rainbow stripes are a cheerful twist on the monkey, and the trick is keeping them flat. I stitch bands in red, orange, yellow, green, blue and purple across the sleeves or chest of a cream or pale brown jumpsuit, using topstitching along both edges so nothing lifts. The tail picks up the same colours along its top. Mismatched booties, one blue and one green, add a playful note. A small plush cloud makes a sweet companion for the photo.
18. Pink Baby Monkey Costume
Pink keeps the monkey shape and softens it. A dusty-rose fleece romper with a pale blush belly is the base, and the hood carries round pink ears with cream centres, embroidered eyes, a smiling muzzle and a darker pink tuft. The tail should be wire-free and short. A bow stitched beside one ear is enough decoration, and I'd leave glitter off a baby completely. The yellow banana, held by an adult, pops nicely against all that pink and tells everyone what animal it is.
19. Blue Baby Monkey Costume
Sky blue with pale gray and navy cuffs makes a monkey that stands out indoors under party lighting. The hood gets padded blue ears, an embroidered face and a navy tuft. I like an alternating blue-and-gray tail here, since it adds pattern without any loose bits. A flat yellow banana patch on the chest or a plush banana beside the baby keeps the theme clear. Warm rooms are the issue at indoor events, so I'd choose cotton over fleece for this one.
20. White Snow Monkey Baby Costume
Plush ivory fabric makes a snow monkey look cosy, but the fuzzy side can feel rough against skin, so I line the romper with smooth cotton. Add a pale gray belly, gray hand cuffs and soft matching booties. The hood gets round ears, embroidered eyes and a white tuft. A rosy fabric muzzle panel gives the pink-faced look without any blush on the baby's cheeks. The scarf is a light blue panel stitched flat across the chest, never a real scarf wrapped around the neck. A plush snowball is the safe parent-held prop.
21. Fleece Baby Monkey Costume
On a cold night, fleece is what I reach for, since it gives warmth without stacking up bulky layers. Choose medium-weight brown fleece with a breathable cotton lining and a front zip that runs low enough for changes. Add the cream belly, a roomy hood, padded ears and embroidered features. Cuffs should be stretchy without leaving marks on the wrists. Keep the tail lightly filled and set high so it doesn't interfere with stroller rides. Once indoors, take the hood off quickly, because babies overheat in fleece faster than adults expect.
22. Knit Baby Monkey Costume
A hand-knit monkey becomes a keepsake, and it's lovely for photos and gentle indoor wear. Knit a brown romper or a sweater-and-pants set in soft washable yarn with a cream belly panel, then a fitted bonnet with knitted ears, a contrasting muzzle and embroidered eyes. Weave in every yarn end securely, because loose ends unravel and tiny fingers find them. A short, firmly attached tail and knit booties without long ties finish it. If the knit feels rough, a cotton bodysuit underneath fixes it.
23. No-Sew Baby Monkey Costume
When there's no time to sew, a brown hooded romper or a brown bodysuit and pants already in the nursery can become a monkey in an evening. Attach a large tan felt belly with removable fabric tape, keeping every adhesive edge on the outside. Layered felt ears go onto the hood before the baby is dressed, and a short felt tail attaches with strong hook-and-loop that comes off for naps and car rides. Brown socks or crib shoes, plus a plush banana held nearby, and the costume is done.
24. Pajama Baby Monkey Costume
For newborns, a footed sleeper with a two-way zip is the gentlest costume base there is. Add a flat cream belly panel and a matching cotton cap with round ears stitched on firmly. Embroider or use fabric marker for the face on the cap, not on the baby. If you add a tail, make it short, flat and removable. The sleeper already covers the feet, though brown booties can go over them briefly for photos. Every costume piece comes off before sleep, and that includes the cap.
25. Baby Carrier Monkey Costume
Babywearing families can make the carrier part of the costume rather than hiding it. Dress the baby in the brown monkey romper with an embroidered hood and footed bottoms, then decorate the outer panel of the carrier with green felt leaves so it looks like a monkey peeking from the jungle. Keep every decoration clear of the baby's face, the straps and the buckles, and never cover the baby's airway. The tail can hang from the outside of the carrier, and the adult can dress as a safari guide.
26. Monkey In A Barrel Baby Costume
The monkey-in-a-barrel turns the stroller into the costume. The baby wears a soft brown jumpsuit with a cream belly, round-eared hood, embroidered features, short tail and brown booties. Light brown fabric printed to look like barrel staves wraps the outside of the stroller, kept well away from the wheels, brakes, straps and air vents. Flat monkey shapes around the sides suggest the rest of the barrel. A plush banana tied to the outside, out of reach, completes the joke, and the baby stays buckled in.
27. Twin Monkey And Banana Baby Costume
Twins don't need matching outfits to look coordinated, and the monkey-and-banana pairing proves it. One baby wears the full brown monkey romper. The other wears a padded yellow banana bunting with a cream centre panel, a green fabric stem on the hood and yellow foot covers. I keep the banana padding thin, because thick padding doesn't belong in a car seat or carrier. A small banana patch on the monkey and a monkey patch on the banana tie the two together in photos.
28. Family Zoo Baby Monkey Costume
A family zoo puts the baby at the centre. The baby wears the standard brown monkey with a cream belly, padded ears, embroidered hood, tail and booties. Parents and older siblings wear khaki shirts and trousers with comfortable shoes and fabric name badges as zookeepers, and another child can be a zebra, lion or giraffe. I'd skip any cage, leash or heavy sign as a prop. A parent holding a plush banana is enough of a gag, and everyone gets a clear role.
29. Royal Baby Monkey Costume
A crown turns the monkey royal. Start with a brown velvet-look romper lined in cotton, since velvet-look fabric can be scratchy on the inside. Add a golden tan belly, padded ears and footed bottoms. The short purple cape is stitched directly to the shoulders, so nothing ties at the throat, and a flat gold fabric crown is sewn onto the hood above the embroidered face. A fabric banana scepter works for parent-held shots, but leave out stick props and stick-on jewels. Gold-trimmed booties make a tidy finish.
30. First Birthday Baby Monkey Costume
A "wild one" first birthday is a natural fit for a monkey. Start with a brown cotton romper with a tan belly, tail, monkey-ear hood and embroidered face. A removable bib or vest carries a big felt number one. The party hat is a small shape sewn onto the hood, with no elastic under the chin. Brown nonslip booties and a yellow banana patch finish it. Choose fabrics that go straight into the washing machine, because cake is going to happen.
Daycare Costume Days and Long Parties
A costume that's lovely for ten minutes of photos can be a nuisance over a whole daycare day. Many centres ask for costumes that are easy to change and safe at nap time, so I plan the monkey to come apart in layers.
- Send the romper on and the hood, tail and any vest in a labelled bag, so staff can add them for the parade and remove them afterwards.
- Put the baby's name on every separate piece. Brown monkey ears look the same as everyone else's.
- Pack a plain spare outfit. Snack time and a long day of play tend to ruin the belly panel at some point.
- Skip anything that needs staff to fasten it the right way. If it isn't obvious, it won't go back on.
For a long family party, the same thinking applies. Let the baby wear the hood for the photos and the arrival, then take it off once they're being passed around. Nobody will forget what the baby was dressed as, and a cooler, happier baby makes the evening easier for everyone.
Every Monkey Here Starts With the Same Hood
Look back through these and you'll notice the same foundation under almost every one: a comfortable romper, a hood with round ears, a contrasting belly, a light tail and soft booties. Change the colour, add a vest, a cape or a crown, and the same baby becomes a sock monkey, a flying monkey, an astronaut or a little royal. Keep the face open, sew every detail down and take the bulky pieces off for sleep and the car seat. Whether you start from a shop-bought jumpsuit or nursery basics, one well-made base can carry you through Halloween, a first birthday and a family photo.
