The research aims to study the types and forms of the outer garments for women, such as the Hijab throughout history, and to study the evolvement of types and forms of the outer garments for women, such as the Hijab, during different eras. This research follows the historical descriptive approach. The research concluded the presence of the Hijab as an outer garment in different eras, as it was used since ancient times to protect the body and cover up, and sometimes for adornment. And there are changes that appeared in the forms of the Hijab, where its shapes, materials, colors, and methods of cutting and sewing it changed during the different eras. It found that there was a relation between wearing the hijab and its functional aspect, as the reasons for wearing it differed, such as wearing it for adornment, and for covering up, and sometimes for protection from climate fluctuations, as the materials from which it was made differed, so wool was used in cold weather and silk or linen in hot weather.
