Hi Yasmin. As you said it is different from country to country (even, from a city to city in the same country). these style of clothing is used in most middle eastern countries (Islamic countries). They are generally used for the same purpose (covering the body). Some countries have strict rules about it like Saudi Arabia or some others are more flexible (I mean people are free to dress as they like) for example Turkey. It is good that in you place, women are free to dress as they like (at least most of them) :)

Hi Matrix thanks for your answer. Yes, you have reason I haven't been in Iran but I was living in Algeria and it's true some people say you comments about it, but isn't the majority.

Hi Generally, these kinds of cloths (long jackets) are called "Manto" (مانتو) in farsi. Well, they can be long or short, tight or loose.... ( I am a boy and I am not so expert in these things :P ) Hijab is not a cloth . It is a about the way, you dress and cover your whole body including your hairs. for instance, if your hair is not covered by scarf, some people may tell that you don't have Hijab or your Hijab is not complete.... or if your "Manto" is too short, again, people may say that your Hijab is not good (because you do not cover your body completely) Usually, religious people complain about women's hijab but these days, women try to stand against these rules and seek their freedom in choosing their own cloths... ( Just my opinion regarding my society)

Hello, thanks for answer. Isn't hijab this is for hair like you say. I think I found how is called, "manto"!

Hi. This style of clothing isn't something I've seen in my country yet. So all I can do is give you my best guess on the right word. I think these would be called "shawls" here. I did a google search with the image and found that these are probably called hijabs. Since hijab is not an English word, it might be best to say "extra long shawl" when speaking with most native English speakers? Also, please correct me if I'm wrong, but I think a hijab is for covering the hair.
