Believe it or not, attractive women have no more self-esteem than less attractive people. They may in fact have less self-esteem because a lot of what others say is quite inconsistent with their actual accomplishments. The world as an attractive woman sees it, is as follows: "No matter what I do, I get complimented. People always say that I do a good job no matter what I do, or how much effort I put into things. Therefore, either I am really good at things or else they are all lying. I think everyone is lying." Hence, attractive women discount much of the compliments others give them. 

Thus, you should think twice before complimenting a good looking woman. The first thing on an attractive woman's mind is deception. Any compliment you give to a good looking women will be scrutinized. She will assume that you have alternative plans for her. Which you probably do. Because a woman looks good, this means that others have lied to her a lot, therefore she will be good at detecting lies

Some more facts are as follows. The more attractive a woman perceives herself to be, the fewer sex partners she has had. However, the better-looking the woman the more popular she is as a dating partner. Thus, women who are good looking date more, but have sex fewer times. They are also difficult to approach because they will only date men who are on the same level as them. As an aside, you can measure the degree to which any girl finds herself attractive and how much self-esteem she has by the people she hangs around with daily. The more unattractive her friends are, the less self-esteem she has, and the more unattractive she finds herself. This can be a bonus for you.

Walsh (1993) adds that attractive women are freer to employ the female reproductive strategy, and (Buss, 1988, 1989) in Walsh, 1993) adds that they have far more choice in terms of partners than less attractive women. Women in this category get to act more like a homosexual (or lesbian) relationship because they have the upper hand. They are the more desirable person in the relationship and hence are able to force men into conforming. Contrary to attractive women, less attractive women feel they have fewer of the attributes that men desire and conform to the male strategy so as not to be left out of the dating game.
