Jeans and Top are not a big deal for zaroon too, that was the only reason he never objects his own sister or even Asmara about wearing them, except that particular situation where he himself saw Osama and random boys mocking Asmara, may be his words were rude but his intention was to protect her, it happens everywhere. And if you are asking about elite society then let me tell you, Zaroon has seen his elite mother and his elite sister failing to be a good wife to their respective partners, especially his mother, his mentality, his ego and his chauvinism are evoked from his own elite lifestyle and upbringing where a wife does not respect and give time to her loving husband, a daughter hardly cares to take her father's advice, a mother does not care to guide her kids, and he clearly never wanted his own married life in such a mess.
and the only reason he married kashaf was because her values and her personality impressed her, not because she is a behenji who does not hang out with boys, please if you have watched the show then do realize the essence of the story. And he saw a woman in Kashaf who is complete, who would be a job holder, a good wife and a good daughter, he saw the balance in her which he never saw in his mother and he never wanted to compromise in his life the way his father has compromised. Zaroon was angry at kashaf not because Osama had proposed her, but because she had hidden it from him, which ofcourse Kashaf returns him back after leaving him because he met asmara and hid it from her. any husband at zaroons or kashaf's place would react, this is close to reality, and it does not make them a jerk, it only alowed Zaroon to grow into a better husband and a better human being, he dealt with Kashaf aftrall the woman who was the hardest nut to be cracked by any other men.
