The majority of the scholars held that a suitor may look at the woman’s face and hands only, and it is not allowable for him to see her in tight-fitting clothes that outline the size of her body. Some scholars, however, held that it is allowable for him to look at what usually appears of her body such as the head and neck.

Allah Knows best.
