Boys' Book Week Costumes: 20 Ideas Beyond Wally and Where the Wild Things Are
If you've been to an Aussie Book Week parade in the last decade, you've seen them — a sea of red-and-white striped jumpers and a handful of furry Max suits from Where the Wild Things Are. Both are wonderful books. Both are also the costume your son's mate is already wearing. If you're hunting for a boys' book week costume that's tied to a real story, comfortable for a school day, and not the same one his classmate picked, this list is for you.
Below are 20 ideas built around books that boys (and many girls!) genuinely read in Australian primary schools — from Roald Dahl heroes to Wimpy Kid to Pokemon. Every costume is something you can buy as a complete set, throw on in five minutes, and link to a book the teacher will recognise the second your child walks into the parade.
Why "Boys' Book Week Costumes" Don't Have to Mean Wally Again
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 Choose Your Own Adventure, even a non-fiction title with a strong character. There's no rule that the book has to be classic, literary, or even old — and there's certainly no rule that boys have to be Wally.
The single biggest unlock for parents of boys is this: let your son pick a book he actually loves. A child who genuinely enjoys Diary of a Wimpy Kid will commit to that costume all day in a way no reluctant Wally ever does. If you start from his bookshelf instead of the shop window, the costume choice gets a lot easier.
A few tips for picking well:
- Comfort wins parade day. Whatever he wears, he'll be in it for 6+ hours. Avoid full headpieces, masks, or anything that scratches.
- One recognisable detail beats five. A wizard scar and round glasses says "Harry Potter" faster than a full Hogwarts kit.
- Pair with something he owns. Most great Book Week costumes are 70% costume + 30% his school shoes and tracksuit pants underneath.
Roald Dahl Heroes (Without Going Straight to Charlie)
Roald Dahl is still the most-read author in Aussie primary schools, but most boys default to Charlie Bucket. Try one of these instead:
1. The BFG. Tan trousers, a long brown vest, big floppy ears, and a dream-catching jar. The BFG is gentle, easily recognisable, and works for boys as young as five. Bonus: it's almost always picked by one kid in the parade — never twenty.
2. James (from James and the Giant Peach). Grey shorts, braces, a striped shirt, and a small plush peach tucked under one arm. It's a character-plus-prop combo that reads instantly, and it's comfortable for a long day.
3. Mr Fox (Fantastic Mr Fox). A russet faux-fur tail, ear headband, and dapper jacket. This one photographs beautifully and works for boys who want something with attitude rather than something cutesy.
4. Charlie Bucket. If your son insists, lean into it properly — patched cardigan, golden ticket in hand, scarf. Better than the half-Charlie that turns up most years.

Fantasy & Adventure Heroes Boys Actually Quote
5. Harry Potter. Yes, it's been done — but the costume still works because boys still love the books. The trick is committing: black robe, House tie (Gryffindor or Slytherin), round glasses, and a wand. Skip the lightning scar drawn on with eyeliner; a temporary tattoo lasts the day.
6. Percy Jackson. Orange "Camp Half-Blood" t-shirt, jeans, sword. Percy Jackson costumes are growing fast in Australian Book Week parades because the books are huge in upper primary. It's also one of the most comfortable costumes on this list — basically a t-shirt and a prop.
7. Aladdin. Vest, harem pants, soft slippers, and a small lamp. Aladdin works for boys aged 4–10 and pairs well if a sibling wants to be Jasmine. It's lightweight enough for an August parade in any Aussie state.
8. Hiccup (How to Train Your Dragon). Green tunic, fur vest, and either a small Toothless plush or a dragon-tail trailing behind. The books are wildly popular in Years 3–5, and most parade audiences immediately recognise the character.
Funny Books Aussie Boys Actually Reach For
If your son's reading list is more "graphic novel" than "classic", these characters are perfect for him.
9. Greg Heffley (Diary of a Wimpy Kid). White t-shirt with a little zigzag print, jeans, and a notebook labelled "Diary". Boys love this because it requires almost nothing he doesn't already own — and yet it's an unmistakable book character on parade day.
10. Captain Underpants. Red cape, white briefs (worn over leggings or shorts!), and a shiny bald cap. It's funny, it's daring, and it's tied to one of the bestselling kids' book series of all time. Some schools cap the "underwear over clothes" thing — check before parade day.
11. Andy or Terry (Treehouse series by Andy Griffiths). Casual clothes plus a small handmade sign that says "13/26/52/91/104-Storey Treehouse". The Treehouse series is on every Australian primary classroom shelf. This is one of the easiest legitimate Book Week costumes a boy can pull off.
12. Cat in the Hat. The Cat is technically gender-neutral, but it's a fantastic option for boys who like bold, silly characters. Striped tall hat, red bowtie, white gloves, black bodysuit (or all-black tracksuit underneath). Available in our book week costumes collection in sizes 3–8.
Aussie Authors and Local Heroes
A Book Week dress-up that ties to an Australian author always lands well with teachers.
13. Geronimo Stilton. Mouse ears, a red tie, a tiny green vest, and a notepad. The Stilton series is huge in Aussie school libraries and surprisingly few kids show up as him. It's a winner for boys in Years 1–4.
14. A character from The 91-Storey Treehouse or Just Tricking! by Andy Griffiths. Casual clothes plus a single bold prop (e.g., a fake banana phone, a paper aeroplane) and a printed name badge. Andy Griffiths himself has said he loves seeing kids dress as his characters at Book Week.
15. Storm Boy. Beach shorts, a striped t-shirt, bare feet, and a stuffed pelican (Mr Percival) tucked under one arm. This is a great choice for boys in coastal schools — it's instantly recognisable as the Colin Thiele classic.
Pop-Culture Books That Absolutely Count
Book Week now formally accepts characters from any book that's been published, including graphic novels and tie-in books. These tend to be the most fun for primary boys:
16. Pokemon — Ash Ketchum. Red cap, blue vest, jeans, and a Poké Ball. There are dozens of officially published Pokemon books, including chapter books and graphic novels, so this is fully legitimate as a Book Week pick.
17. Pikachu. Yellow hooded onesie with brown stripes and red cheeks. Comfortable, warm enough for an August morning, and beloved by boys aged 4–8.
18. Tintin. Blue jumper, beige plus-fours (or rolled-up beige pants), a quiff hairstyle, and a small white plush dog (Snowy). Tintin is a perennial sleeper hit — older boys feel cool wearing it because the books skew slightly grown-up.
Easy Last-Minute Picks With Real Book Connections
If parade day is next week and you need something fast, these costumes go on in seconds and link to genuine books:
19. Captain Hook or Peter Pan. Both characters come from J. M. Barrie's classic. Hook gets the dramatic coat, hat, and hook-hand; Peter gets the green tunic and pointed cap. Brothers can do both for a great Book Week sibling photo.
20. Jim Hawkins (Treasure Island) or Robin Hood. A pirate or archer outfit instantly reads as a Book Week character. Add a small printed quote tag pinned to the shirt — "From Treasure Island by Robert Louis Stevenson" — and there's no doubt about the source.

Boys' Book Week Costumes FAQ
What's the most popular boys' book week costume in Australia?
Wally is still the most-worn boys' book week costume at Aussie school parades — which is exactly why so many parents are now looking for alternatives. Harry Potter, Captain Underpants, and Wimpy Kid (Greg Heffley) are the fastest-growing picks for primary-aged boys.
What size book week costume should I order for my son?
Check the size chart on each product page — Aussie costume sizes generally run by age, but brands vary. If your son is between sizes, size up: a slightly loose costume is more comfortable for a full school day than a tight one, and most chapter-book characters are meant to look a bit oversized anyway.
Can boys dress as characters from graphic novels at Book Week?
Yes. The Children's Book Council brief is "a character from a book", and graphic novels, comics, and book-form Pokemon stories all qualify. Check with your school first if your son's pick is a less-traditional character — most Aussie schools are very relaxed about this.
What's an easy boys' book week costume that doesn't need sewing?
Wimpy Kid (white t-shirt + jeans + notebook), Captain Underpants (cape + briefs over leggings), and Andy or Terry from Treehouse (casual clothes + a printed sign) are all under five minutes to put together and need no sewing at all.
Picking the Right Costume Is Easier When It's a Book He Loves
The boys who have the best Book Week parade are almost always the ones who picked a character from a book they already love. Start with the books on his shelf, work out which character he wants to be, and then find a costume that's comfortable, easy to put on, and built for a full day at school.
