When proposing / before agreeing to marry a woman, how much can a man look at her (body)?

I found the following evidence: > - A lady came to Allah's Messenger (ﷺ) and said, "O Allah's Messenger (ﷺ)! I have come to you to offer myself to you." He raised his eyes and looked at her and then lowered his head. ... (Sahih al-Bukhari) > > - I was in the company of Allah's Messenger (ﷺ) when there came a man and informed him that he had contracted to marry a woman of the Ansar. Thereupon Allah's Messenger (ﷺ) said: Did you cast a glance at her? He said: No. He said: Go and cast a glance at her, for there is something in the eyes of the Ansar. (Sahih Muslim) > > - When one of you asked a woman in marriage, if he is able to look at what will induce him to marry her, he should do so. He (Jabir) said: I asked a girl in marriage, I used to look at her secretly, until I looked at what induced me to marry her. I, therefore, married her. (Sunan abi Dawod) ...'When Allah causes a man to propose to a woman, there is nothing wrong with him looking at her.' (Sunan ibn Majah) This stresses the importance of a man looking at the shape of his future wife's body to avoid any problems after marriage. How much of her body can he see? Hair? Arms and Legs? In tight clothing? Naked? Question: What parts of the body is a man allowed to see when deciding whether to marry the woman or not?
