Children should only have to wear uniform on school event(when vistors come, sports days)
Firstly, your Grammar is Poor. Against your first argument about freedom of choice towards what children wear, if they wear Mufti it is a problem of "Hmm what shall I wear today, a dress, a skirt , a Hoodie", whereas with wearing school Uniform there's no fuss, and most importantly if everyone wears the same then the chance of bullying towards clothing is nill. I do not understand your second argument. Arguing your 3rd point, Usually you wear your uniform twice, so that four days and if its clean then you just wear it another. Obviously the parent would realise if their child has worn the same uniform for a week so if a child has not given their Uniform to their parent then that's really their problem
