Book Day costumes are mostly a craft-table job, not a shopping trip. Clear colors, ordinary clothes, comfortable shoes and one or two signature props are enough to make a character obvious, and a packaged set rarely does it better. I make most of these from closet basics, thrift finds, felt, cardboard and washable makeup, and I've noted how I'd attach each piece so the clothes go back into the wardrobe afterward. The list covers classic storybook heroes, funny picture-book characters and a few grown-up literary figures, so it works for kids, teens, teachers and families. Swap heavy props for light ones and adjust layers to the weather.
A Small Craft Kit Covers Most of These Characters
Almost every costume below is built from the same handful of supplies. If you gather these once, you can make nearly any character on the list in an evening.
- Felt sheets in red, white, black, brown, green and yellow. Felt cuts cleanly and never frays, so ears, badges, bow ties and spikes need no hemming.
- Fabric glue for felt on felt. It stays flexible once dry, while hot glue sets hard and tends to peel off fabric when it bends or gets cold.
- Safety pins and a needle with thread for attaching pieces to clothes you want to keep. A few big basting stitches come out in seconds afterward.
- Cardstock and cereal-box cardboard for hats, crowns, signs and suitcases.
- Elastic cord and hook-and-loop dots to keep headpieces on and to let capes pull away safely.
- Pipe cleaners and craft foam for anything that needs to stand up, like rabbit ears or curly tails.
1. Matilda Book Day Costume
Matilda needs almost no craft work at all. A simple blue knee-length dress over a white Peter Pan collar shirt, white ankle socks, and black Mary Janes or ballet flats. Straight hair with a neat red headband, and a red ribbon at the waist if the dress needs more color. A small stack of light books is the main prop; a handmade library card in the cardigan pocket is the clever extra. On a cold day a navy cardigan can stay on from drop-off to pickup without hiding her.
2. Harry Potter Book Day Costume
Harry Potter is mostly real uniform: a white button-down, gray sweater, black trousers and a burgundy-and-gold striped tie, with a plain black robe or long cardigan on top. Round glasses, a washable lightning mark and slightly messy hair do the face. For school, I'd skip a realistic wand and carry a rolled paper spell scroll or a decorated pencil. The house badge is a quick sewing job: cut a felt shield, blanket-stitch the edge and safety-pin it to the sweater so it comes off cleanly.
3. Where’s Waldo Book Day Costume
Waldo is quick: a red-and-white striped long-sleeve shirt, blue jeans or navy trousers, a red-and-white knit hat and round black glasses. Brown boots, loafers or neutral sneakers handle a full school day. A cardboard tube makes a light walking stick, or swap it for a small travel map. I make the mini camera from a small box wrapped in black paper with a bottle cap for the lens, hung on a ribbon around the neck. It's all everyday clothing, so it suits students, teachers and big groups.
4. The Cat In The Hat Book Day Costume
The Cat in the Hat turns black basics into a character: a black long-sleeve top with pants, leggings or joggers. A big red felt bow tie and a white felt oval on the chest go on next; I hand-baste the oval with large stitches, which takes ten minutes and pulls out afterward without marking the shirt. The tall striped hat works best as cardstock rolled into a tube with red felt stripes glued around it. Paint a small black nose and three whiskers on each cheek, tuck the hair inside the hat, and add black sneakers and white socks. A red book or paper fishbowl is the prop.
5. Alice In Wonderland Book Day Costume
Alice is comfortable enough for a full day of classroom activities. Choose a light blue knee-length dress and put a white pinafore or apron over it, with white tights or ankle socks and black Mary Janes. A wide black headband on hair worn down finishes the head. If you're making the apron, a rectangle of white cotton with a waistband and two ties is all it takes, and it needs no pattern. Carry a toy rabbit, a paper pocket watch or a homemade “This Way” sign, and slip a white cardigan under the apron if it's cold.
6. Dorothy Book Day Costume
Dorothy comes together from familiar pieces: a blue gingham dress, or a blue checked skirt with a white puff-sleeve blouse. White ankle socks and red flats or red sneakers beat glittery heels for walking. Two braids tied with blue ribbon, a basket lined with blue fabric and a small plush dog finish her. If carrying a basket all day sounds hard, I'd make a light cardboard one on a crossbody strap so her hands stay free. A pale blue cardigan adds a layer.
7. Max From Where The Wild Things Are Costume
Max is cozy for a chilly Book Day. A white hooded onesie, tracksuit or matching sweatshirt and sweatpants is the base, with soft felt ears and black felt buttons attached by safety pins from the inside so nothing is permanent. A removable gray or cream faux-fur tail goes at the back; cut faux fur from the back with small snips through the backing only, which keeps the pile long instead of shearing it. A gold paper crown over the hood, held on with elastic, a little pink nose and a cardboard sailboat finish him.
8. Very Hungry Caterpillar Book Day Costume
The Very Hungry Caterpillar starts with a green sweatshirt and green leggings, trousers or joggers. Overlapping circles of light and dark green felt down the front give the segmented body; I glue the circles to each other first to make one flexible strip, then pin that strip on, which is far quicker than attaching each circle to the shirt. A red beanie or hood with purple felt antennae, a little face paint, and green sneakers or black school shoes. Carry a cardboard leaf with round bites cut from one edge, and pin felt fruit to a tote so it doubles as a book bag.
9. Pippi Longstocking Book Day Costume
Pippi is all about mismatching. A patchwork dress, pinafore or oversized tunic over a striped shirt, two different knee-high socks and sturdy brown lace-up boots. Her braids get soft craft wire threaded through the middle and bent outward; I fold the wire ends back on themselves before covering them so there's no sharp tip under the tape. An orange wig works too if it fits snugly. Washable freckles, a plush monkey or travel case, and patches pinned or tacked on with a few stitches make it look homemade in the best way.
10. Fancy Nancy Book Day Costume
Fancy Nancy is the place for every bit of costume jewelry in the house. A sparkly skirt with patterned leggings, a colorful top and a short cardigan or a feather-free cape. Layered necklaces, oversized sunglasses, a jeweled headband and a stack of bracelets, then curls, a high bun or a side ponytail with a large bow. Glitter-look sneakers or decorated flats beat stiff dress shoes. A small purse with paper vocabulary cards finishes her. The secret is clashing colors on purpose so the outfit looks deliberate rather than random.
11. Anne Of Green Gables Book Day Costume
Anne of Green Gables is easy to sew if you'd like a project, since the pinafore is just a gathered rectangle with shoulder straps. Pair a long blue, brown or forest-green skirt with a high-neck white blouse, the pinafore on top, dark tights, and black or brown lace-up boots. Two long red braids are her signature, from temporary color or a natural-looking wig. Light washable freckles, a slate, a stack of schoolbooks or a fabric travel bag, and a straw hat with plain ribbon complete her.
12. Paddington Bear Book Day Costume
Paddington is warm and needs no animal suit. A navy duffle coat goes over brown trousers and a cream sweater, with a bright red floppy hat and brown shoes or boots. A brown beanie with small felt ears under the hat hints at the bear. A small brown nose and a few whisker dots are enough paint. I build the suitcase from a small cardboard box, cover it with brown paper and travel labels, and make the handle from a loop of ribbon glued deep inside so it doesn't tear off. A paper tag on string tied to the coat button finishes him.
13. Peter Rabbit Book Day Costume
Peter Rabbit uses soft garden colors: a light brown sweatshirt with matching joggers, leggings or trousers, and a bright blue jacket or cardigan on top. Make the ears from two layers of felt with a pipe cleaner glued between them so they stand up instead of flopping. A brown headband holds them, and a white pom-pom tail is safety-pinned on. A pink nose and fine whiskers in washable paint, brown sneakers or soft boots, and a basket of felt vegetables make the prop. Preschoolers and younger children are happy in it all day.
14. Willy Wonka Book Day Costume
Willy Wonka starts with a velvet-look purple coat, patterned vest, white shirt and neat trousers, plus a bright bow tie and a tall brown top hat. Soft curls under the hat or a short curly wig, rosy cheeks and defined brows. Brown loafers, ankle boots or lace-ups finish him. A decorated cardboard tube makes a light cane; I wrap it in paper first and add a ball of foil at the top for the knob. Oversized paper candy and colorful paper tickets in the coat pocket add clues, and everything stays soft for a school day.
15. Ms. Frizzle Book Day Costume
Ms. Frizzle is the teacher's chance to have fun. A dark blue or purple knee-length dress gets felt planets, stars, numbers, insects or dinosaurs across it. To keep them removable, I stick each shape onto self-adhesive hook-and-loop dots, though sticky dots can lift on stretchy knits, so a couple of safety pins help there. Bright tights, red, yellow or blue ankle boots and a high red-orange bun or a curly wig finish her. A clipboard, toy magnifying glass or cardboard planet works as the prop, and foam-circle planet earrings are a fun detail. Choose shapes to match the day's lesson.
16. Diary Of A Wimpy Kid Costume
The Wimpy Kid look is a white T-shirt, black shorts or trousers, a lightweight black backpack, white crew socks and black sneakers. The face does the work, so draw the character's features on sturdy white cardstock, cut out eye holes, and glue the mask to a craft stick instead of tying it on. That way it can be lowered whenever needed and never blocks the view while walking. A black-and-white composition notebook labeled as a journal finishes it, and the plain clothes match the book's sketchy artwork.
17. Dog Man Book Day Costume
Dog Man mixes a police-style uniform with friendly dog details. A blue button-down and navy trousers, a felt badge and a simple blue cap. I sew the brown felt ears to the sides of the cap with a few stitches so they hang below the brim without covering the ears underneath. A small black nose and whisker dots in washable paint, black sneakers, and brown gloves if you want paws. Carry a cardboard comic, a paper speech bubble or a plush bone instead of anything that looks like real police kit. A short felt tail on a clip finishes it.
18. The Bad Seed Book Day Costume
The Bad Seed is a funny DIY costume built on a brown sweatshirt or oversized T-shirt with matching bottoms. Cut a large tan felt oval for the front and add darker teardrop seed markings in brown felt; felt doesn't fray, so the edges can stay raw. A brown beanie with a small green felt sprout on top, and brown sneakers or boots. A playful frown is all the makeup it needs. Carry a cardboard book cover, or a sign reading “Bad Seed, Better Choices” for a school-friendly twist. Roomy clothes keep younger students and teachers comfortable.
19. Day The Crayons Quit Costume
The Day the Crayons Quit is the best one on this list for a class or teacher group. Each person picks one bold color and wears it head to toe: shirt, trousers, socks and sneakers. The crayon hat is a cone of colored cardstock with a black paper band around the base; I staple elastic inside the cone so it sits straight. A vertical paper label pinned to the shirt reads as the crayon wrapper. Carry an oversized cardboard letter with a funny crayon complaint, and keep makeup to one small sweep of matching color.
20. Olivia The Pig Book Day Costume
Olivia is crisp red, white and black. A red pinafore over a white-and-black striped long-sleeve shirt, black leggings or white tights, and red ballet flats, Mary Janes or sneakers. Hair goes back under a pale pink ear headband, or a pink beanie with felt pig ears. A small pink nose and rosy cheeks in washable makeup, and a sketchbook, paper crown or red book as the prop. For the curly tail, I wrap pink felt around a pipe cleaner and twist it into a spiral, then clip it to the back of the dress.
21. Ramona Quimby Book Day Costume
Ramona is made from ordinary kids' clothes: denim overalls over a bright striped T-shirt, patterned socks and red or yellow canvas sneakers. A short bob, loose pigtails or tousled natural hair suits her. Carry a lunch box, a library book or a paper name tag; a cardboard “No Smooching” sign is a funny nod to the books. A cardigan covers a cool day, and nothing has to be bought or altered, so every piece keeps getting worn.
22. Amelia Bedelia Book Day Costume
Amelia Bedelia's housekeeping uniform is a modest black or navy dress with a white apron and a detachable white collar. Opaque tights and black flats or low lace-ups, with a neat bun under a small white cap. I cut the cap from white felt and pin it into the bun with two bobby pins; felt holds its shape far better than paper. A light tray with paper food or a duster made from strips of soft fabric, and a stack of instruction cards with literal drawings. Tie the apron firmly and keep it above the knee so no one trips.
23. The BFG Book Day Costume
The BFG works through oversized pieces rather than prosthetics. Cropped brown trousers, a white collarless shirt and a long olive or brown vest, then a weathered jacket one size larger with the sleeves rolled. Brown boots or sturdy lace-ups. The big ears are cut from craft foam, which is light and bends without creasing, and glued to a fabric-covered headband. A neutral beanie covers hair. The dream jar is a clear plastic jar, never glass, filled with colored tissue and battery fairy lights. A light paper trumpet is optional for photos.
24. Curious George Book Day Costume
Curious George is soft brown layers and a few felt details. A brown hoodie with matching joggers or leggings, a tan felt oval on the chest and rounded felt ears on the hood. For the long tail, I sew a tube of brown fleece and stuff it lightly so it hangs rather than sticking out, then pin it at the back. A small brown nose and smile lines in washable makeup, brown sneakers, and a yellow paper hat worn now and then. A plush banana or the storybook is the prop.
25. Mary Poppins Book Day Costume
Mary Poppins looks polished in a white high-neck blouse, long navy skirt and fitted dark jacket, with opaque tights and black lace-up boots on a low heel. A tidy bun sits under a small black hat trimmed with fake daisies and red ribbon. Carry a closed black umbrella for photos only, following school rules, or a light cardboard version. A big carpet-style tote is practical and very her; it's an easy sewing project from two rectangles of upholstery fabric. A red bow tie at the collar finishes her.
26. Sherlock Holmes Book Day Costume
Sherlock Holmes suits older students and teachers who like tailored clothes. Brown trousers, a white shirt and a tweed vest, then a checked cape, short coat or oversized plaid scarf over the top. A deerstalker-style cap and brown lace-up shoes finish the outline. Carry a plastic magnifying glass, notebook and pencil instead of a pipe. A paper clue card tucked into a pocket gives him something to pull out for photos. The textured fabrics look rich, and the separates are comfortable for a full day.
27. Little Red Riding Hood Book Day Costume
Little Red Riding Hood is a white blouse, a red or black knee-length skirt and a lace-up vest or fitted cardigan, with an opaque red hooded cape on top. If you're sewing the cape, fleece is the easiest fabric because it doesn't fray and needs no hem. Cut it short so it never drags. White tights and black Mary Janes or ankle boots, two braids or loose waves, and a wicker basket lined with red gingham holding paper food or a book. Leave out dark makeup and wolf details for school.
28. Goldilocks Book Day Costume
Goldilocks uses soft yellow and blue. A pale blue or yellow dress with a white apron and short puff sleeves, cream tights or white ankle socks and brown Mary Janes. Curly blonde hair with a blue ribbon, or a secure ringlet wig. Carry a light bowl and spoon made from cardboard or plastic. My favorite detail is three small felt bear faces stitched onto the apron in descending sizes, which tells the story without anyone else in costume. Fitted shorts under the skirt and a cardigan keep her comfortable.
29. Captain Underpants Book Day Costume
Captain Underpants has to be layered for school, and that's easy. A skin-tone or white long-sleeve shirt with matching leggings or sweatpants is the fully covered base, with oversized white shorts on top. The red cape fastens with hook-and-loop tabs instead of a tie, so it pulls away safely if it's grabbed. A small black felt waistband detail, a smooth beige cap if wanted, bold cartoon eyebrows, red socks and white sneakers. A handmade comic or cardboard speech bubble with a school-safe phrase gets the laugh.
30. Junie B. Jones Book Day Costume
Junie B. Jones is made for everyday kids' clothes: a bright cardigan over a patterned dress, skirt or denim overalls, with striped tights or loud leggings. Sneakers or black Mary Janes handle a busy day. A high side ponytail with an oversized bow or colorful clips is her hair. Carry a small backpack and a composition notebook with a handmade label, plus child-safe costume glasses if they're comfortable. It should look lively and imperfect, so don't over-coordinate.
31. Fern From Charlotte’s Web Costume
Fern is quiet and comfortable, and the prop does the identifying. Denim overalls over a red plaid or pale blue cotton shirt, warm socks and brown boots or sneakers. Two braids, a low ponytail or natural waves under a straw hat, with a few faux freckles. A plush pig in a light basket lined with checked cloth is essential. I make the spiderweb from white embroidery floss glued across a cardboard ring, with “SOME PIG” written in the middle, and tie it to the basket. A cream cardigan under the overalls covers cool weather.
32. Nancy Drew Book Day Costume
Nancy Drew comes from vintage-style separates: a knee-length plaid skirt, a tucked-in blouse and a mustard, burgundy or navy cardigan, with opaque tights and brown loafers or ankle boots. A smooth bob, ponytail or soft curls. Inside a structured crossbody bag go a notebook, pencil, small flashlight and plastic magnifying glass. A handmade clue envelope marked with a question mark adds interest. Keep the mood curious rather than dark, and the layers let her adjust between classroom and playground.
33. The Little Prince Book Day Costume
The Little Prince is gentle and easy to move in. A pale blue or green tunic over cream trousers, a red sash at the waist and a short yellow scarf. Brown knee-high boot covers over brown shoes or sneakers; I make these from felt tubes with elastic at the top, which go on in seconds. Tousled blonde hair from temporary color or a short wig, a little golden shimmer, and a light cardstock crown. Carry a paper rose under a clear plastic dome, and pin a felt star to the tunic.
34. Coraline Book Day Costume
Coraline stays playful thanks to bright rainwear: a yellow hooded raincoat over a red striped shirt and straight blue jeans, with blue rain boots or blue sneakers depending on school rules. A short blue bob from washable color or a snug wig, light freckles and rosy cheeks. Skip button-eye effects that block vision; instead, glue two oversized black cardboard buttons onto a clue card she can carry. A blue crossbody bag or a homemade stuffed cat finishes her, and the raincoat earns its place on a wet day.
35. The Gruffalo Book Day Costume
The Gruffalo closes the list in cozy brown: a hooded sweatshirt with matching joggers, a tan felt belly and soft purple felt spikes down the back. Rounded ears and curved foam horns on the hood, all kept light so the hood doesn't drag backward. I sew the spikes into the hood seam line with a running stitch rather than gluing, because glue lines stiffen the fabric. A black nose, thick brows and one small green mark near the nose in washable makeup, brown sneakers, and gray felt claws on gloves. A plush mouse makes the perfect story prop.
Attaching Felt So the Clothes Still Get Worn Again
Most of these looks use a child's normal sweatshirt, dress or overalls, so I avoid anything that permanently marks the fabric. Here is what holds up and what comes off cleanly.
- Baste large pieces like the Cat in the Hat's chest panel or the Bad Seed's oval with long running stitches around the edge. Snip the stitches the next day and the shirt is untouched.
- Glue small felt shapes together into one larger panel first, then pin or baste that panel on. It's quicker and far sturdier than attaching dozens of separate pieces.
- Put safety pins in from the inside of the garment so the clasp sits against the fabric, not against skin or within easy reach of small fingers.
- Iron-on adhesive and fabric paint are permanent. Use them only on a thrifted or plain shirt you're happy to keep as a costume.
- Pull off sticky hook-and-loop dots slowly. On delicate knits they can leave residue, which a little dish soap and warm water usually removes.
When You Only Have the Night Before
If the reminder note surfaced at bedtime, pick a character that relies on clothes and paper, not sewing. Waldo, Ramona, Junie B. Jones, the Wimpy Kid and a Day the Crayons Quit crayon can all be made in under an hour from what's in a drawer plus a sheet of cardstock. Lay the outfit out with the shoes, and leave makeup until the morning, when a quick patch test on the wrist tells you whether to use it at all.
Enough Clues, Not Every Detail
None of these costumes needs to copy every illustration. Start with clothing that's already at home, then add the character's colors, the hair, a little washable makeup and one light prop, and that's enough for classmates to name the book. Try hats, capes, masks and shoes on the evening before so nothing gets in the way of moving or seeing. Keep props soft, compact and within school rules. The best result is a costume the wearer forgets they're wearing, so they can spend the day talking about the story instead.
