My sons school is having a Mufti Day for charity.They have to pay the equivelent of 2 Pounds(we are overseas)to wear own clothes,money raised goes to a charity.Thing is I really strongley disagree with supporting this charity.Was thinking of just sending him in uniform as usual,no fuss,"sorry i forgot'".Do you think this is best way to handle it.But he would stand out like sore thumb,rest of school in own clothes.
