DD wants to be Matilda for world book day. Our school hasn’t properly done it before but is this year (it’s been not mentioned/less than half of the children have done it before). Dd has a few blue dresses she could wear but for people that have done world book day before, have you bought proper costumes? I hate waste and buying something for one/two uses but I don’t want her to be the only one who’s just in a normal dress if everyone else will be in proper costumes, but I don’t know if that’s the case?
