When meeting a girl for the first time, perhaps it would be good to get to know her a little before working on attracting her. It sounds like you are making an instantaneous snap judgment about which one you want to attract, based solely on appearance. If that is not the way you want to be judged yourself—if you think actions and behavior and character and personality ought to have something to do with it—perhaps you should accord her the same latitude.
Also girls are not mass-produced Barbies. They may be are attracted to different things. One likes a quiet, dreamy, poetic type, another a life-of-the-party clown, another a sober scientific mind, another a health-and-fitness nut.
Your best bet is to act like the person you are so that someone who likes your type will be able to pick you out.
Forgive me if I am misinterpreting your remarks.
