Hijabs designed especially for girls between the average age of 6 to 13 years. Girls sizes vary greatly in youth to pre-teen years because each girl grows at a different rate, which makes it difficult to pin down the actual age these hijabs are appropriate for. The hijabs are made of stretchy lycra so they can fit a wide range of girls comfortably. For your convenience there is a handly illustration with the approximate size of the hijab's 2 pieces.
