We've found 14 costume ideas on Instagram that will be easy to make or buy in time for World Book Day on Thursday 3 March.
Road Dahl's Matilda is an easy costume to pull off with the one necessary accessory - red ribbon in their hair.
2. Pippy Longstocking
Create Pippy's signature ponytails by weaving pipe cleaners through your child's plaits.
3. Paddington Bear
With some simple accessories - the brown tag, sandwich and small briefcase - Paddington is an easy costume to create.
4. Harry Potter
Either buy a signature cape online or create your own, not forgetting the zig zag forehead scar.
5. Queen Of Hearts From 'Alice In Wonderland'
This one might take a little more planning, but just remember - as many hearts as possible.
6. Stick Man
The famous book character created by Julia Donaldson can be made completely from cardboard (and some green and brown clothes).
7. Witch From 'Room On The Broom'
Another one of Donaldson's characters is the crazy witch from 'Room On The Broom' - the star-topped wand is an essential.
8. James And The Giant Peach
Although the costume for James can be pretty flexible there is the issue of locating a large giant orange ball to resemble a peach.
9. Mrs Twit
From Roald Dahl's 'The Twits', parents can get creative for Mr or Mrs Twit with some backcombed hair and slightly messy clothes.
For children with long blonde hair, no costume is necessary at all - for others a long, blonde wig will do the trick.
11. The Hungry Caterpillar
There are tons of costumes online for the all-time favourite book character - our guess is this one will be a little harder to make.
12. Dr. Seuss' Thing 1 and 2 (or 3)
With a crazy blue wig and a red all-in-one, it'll be pretty obvious who your child is dressed up as.
13. Willy Wonka's Golden Ticket
Who says you can't get a bit creative with the characters?
14. Aslan From 'The Lion, The Witch And The Wardrobe'.
Any lion costume is easy to pick up, just make sure your child can make the fearsome face to match.
