I think she should just go out and make more friends casually.
If the right one appear, then it's time to make the move. I am really for ladies to make the move and go after her dream man.
I advise her to be more learned.
When you are going out with people from higher society, they tend to have critical thinking. They tend to be able to see wider picture , details and implication in the very instant ( If A happens, what next). They like people who don't bitch but look at the bigger picture and take care of his interest.
So this group of people will fall in love with someone who has that same quality as them. Communication is very important. So be more learned and be confident.
