Headscarf: Fashion, culture Religion ?

As I have been researching on different cultures and patterns I became interested in looking at the headscarf. The purpose of the headscarf is used differently by different people. I collected pictures of the different ways they are worn , and how some wear it for religion some for culture some for tradition and some wear it for the simple use of fashion. I have started to wear the headscarf too for religious purposes so I wanted to expand my research about the Headscarf and the different styles and ways they are worn.
