One's style of the dress reveals the human obsession with both novelty and tradition. People use clothing to declare their membership in a particular social group; however, the rules for what is acceptable dress for that group may change. In affluent societies, this changing of the rules is the driving force behind fashions. By keeping up with fashions, that is, by changing their clothing style frequently but meanwhile, members of a group both satisfy their desire for and obey the rules, thus demonstrating their membership in the group. There are some interesting variations   regarding individual status. Some people, particularly in the West, consider themselves of such high status that they do not need to display it with their clothing. For example, many wealthy people in the entertainment industry appear in very casual clothes, such as the worn jeans and work boots of a manual laborer. However, it is likely that a subtle but important signal, such as an expensive wristwatch, will prevail over the message of the casual dress. Such an inverted  status display is most likely to occur where the person's high status is conveyed in ways other than with clothing, such as having a famous face. According to the author, fashions serve all the following purposes EXCEPT
satisfying an interest in novelty signaling a change in personal beliefs displaying membership in a social group following traditional rules
