I meet with a lot of people from that region. From my personal experience almost every Iranian in the US is very Westernized including women who dresses like any other American. But most other Arabs including Saudis I know are still very traditional. Most of Arab women in the US still wear scarves or even burkas. This is just what I have observed, I have no idea how they really think. Not sure if this translates to larger population or not though.

The thing with Iranians is that most of them are ethnically and linguistically Persian. They are mostly Muslim, but then they're Shia, not Sunni; it's the Sunni extremist that tend to go nuts for scarves and burqas.
