We Now Have Book Week Costumes for ASD Kids!
This year we have added something a bit special – we have a whole section on costumes that may be suitable for kids with ASD to wear. For those who ask how we came up with these, I asked my ASD son if he would wear them (the boy’s costumes anyway) and he said yes to these.
These costumes are simple, are minimalistic, have no sleeves or simple sleeves or masks – but are still super cool! We hope you enjoy it!
