Book Week Costume Ideas for Girls 2026: Pretty, Brave and Funny Characters She'll Love

Book Week 2026 runs from 22 to 28 August, and this year's theme is "Symphony of Stories." For parents shopping for girls, this is one of the best themes in recent years. It is broad enough to cover every kind of character: the elegant heroines, the fearless adventurers, and the laugh-out-loud funny ones that steal the show at every parade.

The challenge is not finding a costume that fits the theme. Almost any book character does. The real challenge is picking the right one for your daughter specifically, because an eight-year-old who loves Matilda and an eight-year-old who loves Alice in Wonderland are very different shoppers. This guide breaks the options down by personality, so you can match the costume to the girl rather than guessing.

Blossom Costumes stocks over 1,000 girls' Book Week options, with same-day dispatch on orders placed before 1 pm AET and express delivery Australia-wide. Browse the full girls' Book Week costumes range or keep reading to find the right character first.

Pretty Book Week Costumes for Girls

Some girls have a very clear idea of what they want: something beautiful, iconic, and unmistakably from a book. These costumes are the ones that photograph well, require minimal explanation at the school gate, and cover the most recognisable heroines in children's literature.

Alice in Wonderland

Alice is the single most recognised Book Week costume for girls in Australia. The blue dress, white apron, and blonde headband are immediately familiar to every teacher and student on parade day. Blossom's Alice in Wonderland costumes range from simple dress sets to deluxe full outfits with accessories, and they are available from size 3 through to teenager. If you want a pairing for siblings or best friends, the Queen of Hearts makes an excellent duo.

Dorothy from The Wizard of Oz

Dorothy is a perennial favourite because the gingham dress, ruby slippers, and small wicker basket are a complete look with no explanation required. It is one of the most comfortable Book Week costumes going, which matters a lot when a child has to wear it for a full school day. Browse Blossom's Wizard of Oz costumes for Dorothy, Glinda, and the Wicked Witch.

Little Red Riding Hood

Simple, striking, and instantly recognisable. The red cape over a white or blue dress is one of the cleanest costumes in the Book Week lineup. Blossom stocks several Red Riding Hood options for girls, from tutu dress versions for younger kids to more detailed full sets for primary school age.

Fairytale Princesses

A princess costume fits the Symphony of Stories theme perfectly because princesses appear in the most-read books across every culture and generation. If your daughter has a specific favourite, Blossom's princess range covers Cinderella, Sleeping Beauty, Snow White, Rapunzel, and more. All are available in full sets with accessories included.

Brave Book Week Costumes for Girls

A growing number of parents and daughters want a costume that says something. These characters are the ones who stand up, speak out, and refuse to be told what they cannot do. They also happen to be some of the most interesting costumes to wear all day, because they come with a story your daughter can actually tell.

Matilda

Matilda is the most consistently popular girls' Book Week costume in Australian primary schools, and for good reason. She is a character who loves books, challenges authority, and wins through cleverness rather than physical strength. A simple blue pinafore, white shirt, and a stack of library books is all it takes. Blossom's Matilda costumes are available in a range of sizes and include everything needed for a complete, recognisable look.

Hermione Granger

Hermione is the brave choice for girls aged 6 and up who want a costume that communicates something: that they are clever, capable, and not easily intimidated. The Hogwarts robe is instantly recognisable and surprisingly practical for a full school day. Browse Blossom's Harry Potter costumes for girls' robe options and accessories including wands.

Mary Poppins

Mary Poppins is underrated as a Book Week costume. She is brave in the quiet way: calm in every situation, competent at everything, and completely unflappable. The hat, coat, and umbrella silhouette is one of the most distinctive looks available for both girls and women. Browse the Mary Poppins costumes at Blossom for girls' and adult versions.

Julia Donaldson Heroines

Julia Donaldson's books are among the most read in Australian prep and lower primary classrooms. Zog, the Gruffalo's Child, and Tabby McTat all feature characters who are determined and resourceful. Browse Blossom's Julia Donaldson range for character options that work for younger girls who want something different from the standard fairytale choices.

Funny Book Week Costumes for Girls

The funniest costumes at any Book Week parade are usually worn with the most confidence. These characters get reactions from teachers, draw a crowd, and give your daughter a talking point for the whole day. If your girl has a sense of humour and is not worried about standing out, these are the ones to consider.

Roald Dahl Characters

Roald Dahl is responsible for some of the great villains and mischief-makers in children's literature. The Witches, Miss Trunchbull, and the Twits are all characters built for dramatic effect and maximum impact at a parade. Browse Blossom's Roald Dahl costumes for a range of Dahl-inspired looks that work across age groups.

Gangsta Granny

David Walliams' Gangsta Granny is one of the funniest Book Week costume choices available, and it works brilliantly across age groups. A grandma outfit worn with exaggerated accessories and a cheeky expression gets a laugh from every teacher in the building. Browse Blossom's David Walliams costumes for this and other Walliams character options.

Animal Characters

For younger girls and toddlers, a well-chosen animal costume is often the funniest and most comfortable option. The Gruffalo's Child, barn owls from Owl Babies, a koala or a parrot can all be tied to a specific book without needing an elaborate explanation. Browse Blossom's animal costumes for soft, comfortable options that work for prep through to Year 2.

How to Choose a Costume She Will Actually Wear All Day

This is the most practical question on Book Week morning. A gorgeous costume means nothing if your daughter refuses to put it back on after recess. There are a few things worth considering before you buy.

• Start with the character, not the costume. A child who loves Matilda will stay in the costume all day. A child who was handed a costume picked by someone else may not. Let her make the call if she can.
• Check for comfort above the hemline. Headpieces, wigs, and hats are often the first things to come off. If the character requires a specific hair accessory, test it at home first.
• Winter layers matter in August. Book Week falls in the middle of winter across most of Australia. Make sure the costume works over a long-sleeve layer or has a cardigan or coat that does not ruin the look.
• Size up if she is between sizes. A slightly bigger costume worn over clothes is far better than a perfectly sized one worn without them on a cold August morning.

Frequently Asked Questions

What is the Most Popular Book Week Costume for Girls in Australia?

Matilda has been the most-worn girls' Book Week costume in Australian primary schools for over a decade, followed closely by Alice in Wonderland and Hermione Granger. If you want something tied to a well-known book but less likely to be duplicated by half the class, Mary Poppins, Dorothy from The Wizard of Oz, or a Roald Dahl villain are strong alternatives.

Does My Daughter's Costume Need to Match the Symphony of Stories Theme Specifically?

No. The 2026 theme is designed to include any book character. Your daughter does not need to dress as someone connected to music or storytelling literally. Any character from any book qualifies. The theme celebrates the diversity of stories, not a single genre or character type.

When is Book Week 2026?

Book Week 2026 runs from 22 to 28 August. Most schools hold their costume parade on the Thursday or Friday of that week. Check your school newsletter for the exact day as it varies by school.

Blossom Costumes dispatches orders the same business day when placed before 1 pm AET. Express delivery is available Australia-wide.
