Book Week 2026 runs from 22 to 28 August, and this year's CBCA theme is "Symphony of Stories". If your school has already sent the parade note home — or you just know it's coming — this guide rounds up the best Book Week costume ideas for 2026, organised the way parents actually shop: by who's wearing it and how much time you have.
Every costume idea below links to a stocked range, so nothing on this list is a craft project you have to start from scratch. Pick a character, check the size, and you're parade-ready.
When Is Book Week 2026?
The Children's Book Council of Australia (CBCA) Book Week runs Saturday 22 August to Friday 28 August 2026. Most schools hold their dress-up parade during that week, with many scheduling it for the Friday — but check your school's newsletter, because plenty of schools run their parade earlier in the week or even the week before.
The 2026 theme, Symphony of Stories, celebrates the way stories work together — which makes it a great year for group costumes, book-series characters, and anything musical or storytelling-themed. We cover theme-specific ideas further down.
If you're ordering online, two dates matter more than any other: place standard-post orders by 19 August, and express orders by 12pm on 24 August, to have the costume in hand before the week wraps up. Earlier is always safer — August is the busiest costume month of the Australian school year.
Book Week Costume Ideas for Girls
Girls' Book Week searches lean heavily toward strong storybook heroines, and the most-loved picks hold their place year after year:
- Matilda — the most popular girls' Book Week costume in Australia, and an easy one to wear all day: a simple blue dress, a red ribbon, and a stack of books. Our Matilda costume is an officially licensed Roald Dahl design.
- Little Red Riding Hood — instantly recognisable from the hooded cape alone. The Little Red Riding Hood costume pairs a fairy-tale dress with the classic red cape.
- Wenda — the search-and-find favourite in red and white stripes. A girls' Wenda costume comes with the striped top, skirt, hat and glasses, so the whole look is sorted in one box.
- Goldilocks — a sweet classic for younger girls, and one teachers always recognise. See the Goldilocks costume with its storybook pinafore styling.

Book Week Costume Ideas for Boys
The boys' list is led by one striped icon, with adventure characters close behind:
- Where's Wally — still the single most-searched Book Week character in Australia. The kids' Where's Wally costume includes the striped shirt, trousers, bobble hat and glasses.
- Willy Wonka — the chocolate factory showman is a parade favourite that photographs brilliantly. The Willy Wonka costume is part of the licensed Roald Dahl range.
- Peter Pan — for the kid who refuses to grow up. The Peter Pan costume works for boys and girls, with the feathered hat included.
- The Gingerbread Man — a fun, comfortable pick for younger boys who want something different. The Gingerbread Man costume is a soft three-piece suit that's easy to wear over school clothes.
The full boys' Book Week costumes range covers everything from classic storybook characters to adventure heroes.
Easy & Last-Minute Book Week Costume Ideas
If the parade note surfaced from the bottom of the school bag with days to spare, these ideas deliver a complete character with minimal effort:
- A wizard school robe — one robe, instant storybook wizard. A kids' wizard robe goes straight over school clothes, which makes it the fastest full-character look on this list.
- Striped character looks — anything in red-and-white stripes reads as a search-and-find character from across the playground. Add round glasses and you're done.
- Hooded capes — a red hooded cape over a plain dress is Little Red Riding Hood; the same trick works for many fairy-tale characters.
- Character accessories over uniform — a bobble hat, a pair of round glasses, or fairy-tale props can carry a whole costume when there's no time for a full outfit.
The main Book Week costumes range has filters for age and size, and the kids' Book Week costumes section narrows it to school-age picks. For genuinely last-minute orders, express post (ordered by 12pm on 24 August) is the safety net. For a full breakdown of every easy option, see our dedicated Easy Book Week Costume Ideas 2026 guide.
Book Week Costume Ideas for Teachers & Adults
Teachers carry Book Week as much as the kids do — and the best teacher costumes are the ones that survive a full day of classroom duty:
- Mary Poppins — practically perfect for teachers in every way. The adult Mary Poppins costume includes the Victorian nanny jacket, skirt, hat and carpet-bag styling.
- The Mad Hatter — a tea-party favourite that pairs perfectly with a class full of Wonderland kids. See the adult Mad Hatter costume.
- Dorothy — the gingham classic from Oz. The adult Dorothy costume is a licensed storybook design with the hair bows included.
- The Queen of Hearts — for the teacher who wants to make an entrance. The Queen of Hearts gown comes with the crown.

Group, Family & Class Costume Ideas
"Symphony of Stories" is the perfect excuse for a coordinated group costume — and Wonderland is the strongest single-book cast you can dress a group from:
- Alice in Wonderland group — Alice, the Mad Hatter, the Queen of Hearts and friends cover any group size, with kids' and adult versions of most characters in stock.
- A search-and-find family — Wally for one child, Wenda for another, and striped tops for the rest of the family. Simple, recognisable, and brilliant in parade photos.
- The Roald Dahl line-up — Matilda, Willy Wonka and friends from the licensed range make an instant author-themed group, which suits the 2026 theme's celebration of storytelling.
- Fairy-tale mash-up — Little Red Riding Hood, Goldilocks and the Gingerbread Man side by side turn a group of friends into a walking storybook shelf.
For teachers planning a whole-class theme, picking one book and mixing full costumes with simple accessory looks keeps it achievable for every family's budget and time.
Matching Your Costume to the "Symphony of Stories" Theme
The 2026 theme doesn't require a music-themed costume — any beloved book character fits, because the theme celebrates stories coming together. That said, if your school is leaning into the theme:
- Characters from book series (rather than standalone titles) nod to the "symphony" of connected stories.
- Group costumes from one book — a Wonderland cast, a Dahl line-up — literally put multiple stories' voices side by side.
- Musical storybook characters and performers, from pied pipers to singing princesses, take the theme at its word.
When in doubt, the character your child actually loves beats a forced theme tie-in every time. Teachers see the difference between a costume worn with joy and one worn under protest.
Sizing, Ordering & Key Dates for Book Week 2026
A quick checklist to get the costume sorted without the last-week scramble:
- Confirm the parade date with your school — it's often Friday 28 August, but not always.
- Order by 19 August for standard post, or by 12pm on 24 August for express, to be safe for parade week.
- Check the size chart on each product page — Book Week costumes span toddler through teen sizes, and adult cuts for teachers run XS through plus sizes on many lines.
- Do a try-on the weekend before so there's time to swap sizes if needed.
- Orders placed on weekdays before 2pm AEST dispatch same day from our Melbourne warehouse.
