Islam doesn’t provide an exact description about what Muslim women can wear. That’s the reason why Muslims from all over the world have different forms of hijab. But it makes clear that the head and body of the woman should be covered in such a manner that the hair and figure should not be displayed. The book provides guidelines that govern behavior as well. For example, the verse states, “…say to the believing women that they should lower their gaze and guard their modesty; that they should not display their beauty and ornaments except what must ordinarily appear thereof” (Quran 24:30-31)
