Self-esteem is the main factor in how people see themselves and is closely related to the image they project to others, according to About.com. Overall attractiveness is based on physical attractiveness, which is culturally biased, together with charisma, charm and other factors that are dependent on self-esteem.
One's self-perception of attractiveness is based on factors that include how one perceives the attention, or lack of attention, one receives from others. There is no universal model of attractiveness because beauty is completely subjective and depends on individual perspective. The perception of attractiveness is a matter of one's environment, culture and personal beliefs.
