Clearly attractiveness is in parts a choice, how you dress, how you comport yourself, how healthy your body appears etc. Those choices signal positive qualities. For example dressing in a way that is perceived as attractive could signal social intelligence (being able to read society's unwritten rules about the semantics of clothes), having a body that appears healthy shows the ability to defer gratification, future orientation etc. All of which are qualities that may be helpful in various kinds of jobs.
