Girls' Book Week Costumes: 25 Storybook Heroines Aussie Kids Love
Ask any Aussie mum what her daughter wants to wear to the Book Week parade and you'll often hear the same three names — Matilda, Hermione, and "a princess from any book at all, please". They're brilliant choices, and they're also the ones turning up five times in every Year 2 line-up. If you're after a girls' book week costume tied to a real story, comfortable for a long school day, and a little more interesting than the default, this list is for you.
Below are 25 ideas built around heroines that girls genuinely read in Aussie primary schools — from Roald Dahl heroines to Pippi Longstocking to Billie B Brown. Every one of these characters comes from a book your daughter's teacher will recognise the moment she walks into the parade, and every costume can be pulled together with a single set plus shoes she already owns.
Why "Girls' Book Week Costumes" Don't Have to Mean Another Princess
Book Week in Australia falls in the third week of August, and the brief from the Children's Book Council is simple: dress as a character from a book. That's it. The book can be a picture book, a chapter book, a graphic novel, a verse novel — even a non-fiction title with a strong character. There's no rule the heroine has to be a princess, and no rule she has to be sparkly. Half the most memorable girls in children's literature wear plaits and gumboots.
The best unlock for parents of girls is the same one that works for boys: let her pick a book she actually loves. A daughter who's reread Matilda four times will wear that costume with conviction all day. A daughter dressed as a generic fairy because "everyone said it was easy" tends to take the wings off at recess.
A few practical tips before we start:
- Plaits and hair detail do half the work. A red ribbon, two French plaits, or a single side braid can carry an outfit further than any prop.
- Pick one signature item. Anne of Green Gables = red plaits. Pippi = horizontal plaits with wire. Matilda = blue ribbon and a stack of books. One detail, instantly read.
- Layer over school basics. Most great girls' Book Week costumes are a dress or pinafore plus the white socks and black shoes she already owns.
Roald Dahl Heroines (Yes, More Than Matilda)
Roald Dahl is the most-borrowed author in Aussie school libraries, and his girl characters are some of the strongest in children's lit. Matilda is the default — try one of these first.
1. Matilda Wormwood. Blue pinafore, white blouse, red ribbon, and a stack of library books tucked under one arm. Add a chalk-and-blackboard prop if she wants to lean into the "moves things with her mind" bit. Comfortable, instantly recognised, and a strong all-day costume.
2. Sophie (from The BFG). Pale nightgown, bare feet (or white socks for parade-day comfort), and a dressing-gown thrown over the top. If her teacher quizzes her, the line is "I'm the human bean the BFG took to Dream Country". Almost no one else will pick Sophie, and the costume is essentially pyjamas — a parent-friendly win.
3. The Enormous Crocodile's nemesis — Trunky, Roly-Poly Bird, or Muggle-Wump. A creative pick for a girl who loves the picture books over the chapter books. Browns, greens, and a small soft-toy prop carry the look.
4. The Witches' Grand High Witch — kid-friendly version. Long black dress, fingerless gloves, a single mask prop she can carry rather than wear. Not for every age — best for Year 4+ — but a strong choice for a girl who's just discovered the book.
Heroines from Aussie-Beloved Chapter Books
These series live on every classroom bookshelf in Australia, and the costumes are some of the easiest to pull together.
5. Billie B Brown. Sally Rippin's Billie is in nearly every Year 1–3 reading nook in the country. A red tee, denim shorts, scuffed sneakers, and a single ponytail tied high — done. Add a small backpack and she's parade-ready in five minutes.
6. Hey Jack's friend — Scarlett. If a Billie costume risks being duplicated, swap to her bestie. The look is similar but with a blue or striped tee.
7. Clementine Rose (from Jacqueline Harvey). A neat pinafore-style dress and a small soft-toy pig (Lavender) under one arm. Skewers right to the book for any teacher who's read it aloud.
8. Alice-Miranda (also Jacqueline Harvey). Boarding-school pinafore, white blouse, knee-high socks, and a friendly grin. Probably the easiest "school uniform + character" mash-up on the list.
9. Olivia from Olivia (Ian Falconer). Red dress, white pinafore, black tights, a small painted nose. Picture-book recognisable across every age group from Prep to Year 3.
Classic Storybook Heroines That Still Land in 2026
These characters are decades old and still on shelves — most teachers will recognise them on sight, which is half the parade-day battle.
10. Pippi Longstocking. Horizontal plaits (a length of wire threaded through helps them stick out), mismatched long socks, a patched dress, and a face full of freckles drawn on with eyeliner pencil. One of the most fun, low-budget costumes in the whole genre.
11. Anne of Green Gables. Two long red plaits (a wig if needed), a straw hat, a green or brown pinafore, and a small carpetbag. Strong choice for any girl who's just finished the series.
12. Heidi. A simple dirndl-style dress, white blouse, an apron, and a hair bow. Works well for younger girls (Prep–Year 2) where comfort matters most.
13. Pollyanna. A long pastel pinafore dress, white socks, a straw hat, and a hand-written "Glad" sign. Niche but a teacher-pleaser.
14. Mary Lennox (from The Secret Garden). Brown or olive pinafore, a small wicker basket of fake greenery, sturdy boots. A quiet, dignified choice.
Heroines from Modern Series Girls Actually Read
If your daughter is reading these in 2026, the costume will land with her classmates too.
15. Hermione Granger. Hogwarts robe, white blouse, grey skirt, striped tie (Gryffindor red-and-gold), and an armful of books. The Hermione we'll see fewest of is the first-book Hermione — bushy hair, no makeup, fully focused on schoolwork. Lean into that.
16. Luna Lovegood. A more original Harry Potter pick. Radish earrings, butterbeer-cork necklace, Spectrespecs, blonde wavy hair, and a copy of The Quibbler held upside down. Stands out in a parade full of generic witches.
17. Annabeth Chase (from Percy Jackson). Orange Camp Half-Blood tee, denim shorts, blonde hair pulled back, and a Yankees cap. Easier to assemble than it sounds and instantly read by any Year 4+ reader.
18. Wonder's Via Pullman or Summer. A great quieter pick for a girl who's read Wonder. School uniform plus a kindness-themed pin or "Choose Kind" badge.
19. Greg Heffley's sister or mum — or skip to Rowley's mate Abigail. Wimpy Kid is so often a boy default that an Abigail or other side character feels fresh.
20. Tree House series — Terry's daughter or the princess in disguise. If your daughter loves Andy Griffiths and Terry Denton, the Treehouse books have plenty of female cameos worth a costume.
Picture-Book Heroines for Prep and Year 1
For the youngest readers, picture-book characters give you the easiest, most photogenic costumes.
21. The Very Cranky Bear's Moose, Lion, Zebra, or Sheep. Mem Fox and Nick Bland's storybooks are everywhere in Aussie pre-school book corners. A sheep onesie or a striped zebra dress works beautifully — and the book is in every public library.
22. Possum Magic's Hush. A grey possum hat, soft grey dress, Australian native flowers in her hair. Mem Fox again — and almost every Aussie teacher knows the book.
23. Wombat from Diary of a Wombat. A simple brown dress or tracksuit, ears headband, a small carrot prop. Jackie French is on the National Curriculum reading list — teachers love a Wombat.
24. Lulu (from Camilla Reid / Lucy Cousins-style picture books). A bright yellow dress, red wellies, a small backpack, and pigtails. Easy and very Prep-friendly.
25. The Tiger Who Came to Tea's girl, Sophie. A simple dress, a teacup prop, and an orange tiger soft toy. The book is a Book Week perennial in every Aussie primary library.
How to Tell If a Girls' Book Week Costume Will Actually Work on Parade Day
Before you commit to a costume, run it through three quick checks:
- Can she sit cross-legged in it? Most Book Week parades end with the kids on the floor for assembly. Tight bodices, layered tulle, or stiff capes all become problems by 10am.
- Will the teacher recognise it from twenty metres? If the answer is "only if she's holding the book", add a second cue — a name badge, a ribbon, a signature prop.
- Is one piece of it something she already owns? White socks, black shoes, plain leggings, a hair ribbon — these basics turn a costume from "fancy dress hire" into "ready to go" in five minutes.
If you're stuck choosing between two ideas, the book week costumes collection on the Kids site has filters for age and theme that narrow it down quickly.
FAQ — Girls' Book Week Costumes
What is the most popular girls' book week costume in Australia? Matilda has been the most-worn girls' Book Week costume in Aussie primary schools for at least a decade, followed by Hermione Granger and the Cat in the Hat's Thing 1 / Thing 2. If you want a costume that's tied to a beloved book but won't be duplicated by half the class, Pippi Longstocking, Luna Lovegood, and Sophie from The BFG are all stronger picks for 2026.
What's a good last-minute book week costume for a girl? Sophie from The BFG (a nightgown and dressing gown), Matilda (any blue pinafore plus a stack of library books), and Possum Magic's Hush (a grey dress and Australian native flowers in her hair) can all be assembled the night before without buying anything new. For a fully made-up option, the girls' book week costumes range ships across Australia in a few business days.
What can a girl wear to book week if she doesn't like dresses? Pippi Longstocking (patched shorts and long mismatched socks), Annabeth Chase (orange Camp Half-Blood tee and denim shorts), and Billie B Brown (red tee and shorts) are all girl-character costumes that don't require a dress at all. Tomboy book heroines exist in great numbers — they just don't get marketed as often.
What are the rules for book week costumes in Aussie primary schools? Most Aussie primary schools follow the Children's Book Council brief — the costume must be tied to a character from a book. Schools usually ask for closed-toe shoes, no full-face masks, and nothing that needs to be plugged in. Beyond that, individual schools may publish their own dress-up day notes — check the parade information sent home a week or two before the event.
A Last Word for Aussie Parents
The girls who have the best time on Book Week parade day are almost always the ones wearing a character from a book they love — not the one that looked easiest in the shop. Start from her bookshelf, pick the heroine she already quotes at the dinner table, and let one signature detail (a red ribbon, two long plaits, a stack of books) do the heavy lifting.
If she's still deciding, browse the full girls' book week costumes collection or the broader storybook costumes range — every set ships across Australia in time for the third week of August.
