Its not a dress code. I have already checked the material and all it says (and I quote)
"Children should be dressed in proper dress (i.e satar)"
Off course I'd have no objection had it been the dress code and to be frank its not the problem of Pants or no Pants. Its only going to bug me if wrong concepts of everyday live are taught.
I have not read posts after this.
For the sake of giving you a different perspective:
So if they make it dress code to be shalwar Qamiz, you will be Ok with that and will not question again?
Will you question why Shalwar Qamiz is dress code or agree just like you agreed to pant and shirt for karate.
I assume you did not question Karate/Martial art dress code.
Now if your child was wearing any clothes and was going to Karate and you did not have time, you would have taken all efforts to change his/her clothes in the car or on the way wouldn't you?
