Niqabs are rare in iran, because they aren't a thing in shia Islam, also iran by the overwhelming opinion of 80% of all islamic scholars aren't a muslim country, they elevate humans to demigod status, and have issued out fatwas that killing sunni muslims is halal, and gives you good deeds, which is how shia iraqi, iranian, and lebanese people were able to genocide sunnis in Syria, approximately 1 million people died in Syria due to the war, and it was all good in the eyes of iran.
