From Matilda to the BFG, these easy costume ideas for boys and girls are great for when schools are celebrating Roald Dahl Day!

Roald Dahl still holds the crown for creating some of the most timeless characters for kids to dress up as.

With so many creepy creatures and brave boys and girls to choose from, is it any wonder that schools are overrun with Matildas, witches and BFGs every year?

We've put together some of our favourites below to help you dress your little Roald Dahl fan.

Dress your little one in a shirt and tie – or a yellow dress if they want to go as Mrs Fox – and pair it with a mask.

Hey presto, you have yourself your very own Fox!

See our step-by-step instructions for an easy Fantastic Mr Fox costume.

Or, if you'd rather buy your costume you can buy a mask and tail set from Amazon for under £5 here.

Messy hair, a drawn on monobrow and a stripy top – and your kids are good to go.

Add in some wooden walking sticks for extra effect.

All you need is a shaggy wig and an even shaggier beard – if it's got some old bits of food in it, even better!

All you need is a golden ticket, a lollipop, a homemade visitor pass and a pretty dress.

If you want to go all out, we recommend this amazing, officially-licensed and ready-made Veruca Salt costume, available on Amazon.

Spoilt brat Veruca Salt famously demanded: 'Daddy, I want a squirrel!'

Dust off your old beanie baby collection to make this costume work.

Decorate a no sew tabard made out of gold fabric for this unusual idea.

All you need is a black wig, a top hat, colourful glasses and gloves for this eccentric Roald Dahl character.

Check out our step-by-step guide to an easy Willy Wonka costume.

Creating Willy Wonka's hat is a great World Book Day activity.

Try looking out for a cheap top hat in a charity shop or a jumble sale. Decorate the hat with ribbons and feathers ... the crazier, the better!

Dress your child in some striped pyjamas and add a flat cap if you've got one.

Then use talcum powder to make your child's hair look grey.

Voila, Grandpa Joe is ready.

Dress your child in a brown top and white leggings or tracksuit bottoms. Then use white ribbon or fabric to create a 'dungaree' effect.

Finally, paint your child's face orange and use a green hairspray on their hair. (Most hair sprays are usually only suitable for use on children aged five and over – always check the label.)

Dress your child in a red stripy top and pop a cushion underneath to make a big tummy. Secure it in place with a belt.

Then add black rolled-up trousers or jeans, trainers and a huge Wonka bar made from a piece of card.

For extra points, add chocolate smears around your child's mouth using face paints.

To make the crocodile head, take a large cardboard box wide enough to fit over your child's head.

Cut along lengthways to make the bottom look like sharp teeth. Then paint the box green – don't forget to cut out eye holes for your child to look through.

Finally paint the 'teeth' white before dressing your child in green clothes and adding a green no-sew cape.

You'll need to buy a flesh-coloured swimming hat and stick on cotton wool at the sides to make grey hair.

Cut some big ears out of cardboard and stick onto a headband. Then dress your child in trousers (sew on patches if you have time), along with a white shirt and waistcoat.

For added BFG effect, why not cut a trumpet out of cardboard for your child to carry as well?

... SO funny!

The costume is really simple – dress your child in a shirt, tie, school trousers and blazer.

To make the giant peach, simply blow up a large, orange balloon. Or, if you have time, you could make a papier-mâché peach.

Creating a Roald Dahl costume is a wonderfully whimsical way to celebrate the beloved author's magical characters. Start by choosing your favorite character – perhaps a cunning Mr. Fox or a whimsical Willy Wonka. For Mr. Fox, dress your little one in a smart shirt and tie or a yellow dress for Mrs. Fox, and don't forget the essential fox mask! If crafting isn't your thing, fear not, as there are mask and tail sets available for a quick fix on Amazon. No matter which character you choose, with a pinch of creativity and some basic wardrobe staples, you'll have a fantastic Roald Dahl costume in no time!

Embracing the sweet and nurturing Miss Honey's style from Roald Dahl's 'Matilda' is simple and adorable. Miss Honey is the epitome of a kind-hearted teacher, and her look reflects this. Find a pretty dress, perhaps in soft pastels, pair it with a prim cardigan, and accessorize with a bunch of yellow flowers for a touch of warmth. Finally, add a pair of round-rimmed glasses to achieve that quintessential, studious vibe. This getup isn't only perfect for kids but also makes for a charming and easy World Book Day outfit for teachers!

Channeling the brilliant and brave Matilda is a favorite for World Book Day. To dress like this iconic Roald Dahl character, look for a blue dress – Matilda's signature outfit in many interpretations. Add a red ribbon in the hair for that classic bookish look, and perhaps carry a stack of books to show off Matilda's love for reading. For a prop, you might even create your very own "newt-in-a-jar" to replicate one of the most memorable moments from the story. Step into Matilda's shoes and let the magic and mischief ensue!

Roald Dahl Day invites a parade of fantastic characters, so the possibilities are endless! Choose your favorite character and get creative. If you're leaning towards the chocolate factory vibe, an oversized purple coat and top hat will transform you into Willy Wonka, while a red wig and a sprinkle of green on your cheeks will turn you into a mischievous little Oompa Loompa. For the fans of 'The BFG,' a pair of big ears and a homemade trumpet will bring your giant costume to life. Whichever character you decide upon, wear it with a big smile and a playful attitude to capture the spirit of Roald Dahl!
