This year's Dahlicious Dress Up Day is part of the biggest Roald Dahl Day party of all time.
On 13 September, Roald Dahl's 100th birthday, schools and groups across the globe will be dressing up, having a party, and donating their marvellous money to Roald Dahl's Marvellous Children's Charity.
The annual Dahlicious Dress Up Day raises money to help provide Roald Dahl nurses and family support to children in the UK living serious, rare and undiagnosed conditions.
And everyone's invited! Sign up now and start planning your party
It's not often we take a register of Oompa-Loompas, Big Friendly Giants and Fantastic Mr Foxes, but it was wonderful!
It was one of the best days we have had. All the children dressed up and it ranged from Esio Trot the tortoise to Willy Wonka. Everyone had a fantastic time.
It's a fantastic opportunity to celebrate a wonderful author and raise money for charity. Children and teachers always enjoy it and support it fully.

It's a really fun day (I spent last one dressed as a giant peach!) the children get very involved and enjoy themselves.
