Requirement to see woman before marriage proposal and ruling on a woman's ability to show her beauty to the potential husband

Fatwa Question or Essay Title: 
If a man makes a proposal of marriage to a young woman, is it obligatory for him to see her? Also, is it correct for the young woman to uncover her hair and to reveal her beauty more for her fiance?

There is no objection, but it is not obligatory. Rather, it is preferred for him to see her, and for her to see him. This is because the Prophet ordered the suitor to look at her, because that is more likely to produce harmony between them, so if she uncovers her face, hands and head for him, there is no objection, according to the most correct opinion. But it is not permissible for him to do so, while being alone with her; rather, her father, her brother or another must be present with her.
