1: Only those men who were looking to get married went to the fields to look.
2: The women attempted to convince the men to marry them by looking at their Beauty, Yichus, and if they had neither, tried to convince them to marry “Leshem Shomayim”.
I infer that women who are looking to get married should “show off their beauty” to convince their prospective husband to marry them, if it is is a place which is only Tachlis (the modern comparison MIGHT be a date). A wedding would not qualify.
