Hope this helps…
From a teacher’s perspective, all costumes are so welcomed. And those that don’t want to - it’s fine too!
It’s not about the best costume, but exciting the kids into the love of reading.
An idea for future book day, which will hopefully help those with all budgets and all time budgets too… this year we focused on adjectives.
It allowed those who wanted to still dress up as a character to do so, but encouraged them to think about adjectives to describe their character. But also those that don’t particularly like character dressing, were able to come as an adjective. Therefore, children and parents could easily use already existing clothes to create fantastically creative adjectives and for all ages too…
From colourful (put on all their colourful clothes) / magical (had anything with unicorns on ) / camouflaged (had an appropriate jumper) / disguised (wore a hat and fake moustache) / flexible (wore their gym wear).
It was our best world book day yet! The children’s ideas were fantastic and it allowed all to participate at the level they wanted to.
My son went as lazy - pjs and an eye mask with his adjective on.
My daughter fully embraced the character dressing and went as Matilda (writing her adjectives on her red ribbon in her hair) - and she ‘gently encouraged’ me to go as Miss Trunchball!
Even if it’s not your school’s theme - I can’t see any teacher not embracing the idea of coming as an adjective!
