The word hijab is referred to as head cover, varies according to the cultural conditions and laws of each country.
Hijab is not limited to chadors. Hijab is sometimes defined in other defenition, such as long manteaus and scarves. The manteau covers the body to above the wrist, so that the neck and underwear are not visible.Its color and model do not attract non-mahrams' eyes.
There was a kind of Hijab before Islam, and even before the birth of Christ, in the paintings and images the lower part of the body had been covered. 
European Muslim women who are young, have been successful not only in introducing Hijab as a symbol of the Islamic identity and the supreme human personality but also in turning their Hijab into a fashion by choosing pants, long dresses, and colorful scarves.
