People wear clothes for the obvious reason that it is essential to protect their bodies against different weather conditions. Clothing shields them from the sun, the rain, snow storms, and the fluctuating temperatures to which they are commonly exposed on a daily basis.
But dress has since earliest times also been used to satisfy other needs, most obviously the universal human concern to enhance the appearance of the wearer. In some situations, doing so serves to reinforce social and political hierarchies, while in others it has played an important role in rituals linked to, for example, courtship or initiation.
Regardless of the context or purpose, people rely on a host of accessories to mark aspects of their identity. This includes permanent body modifications such as scaring and tattooing, and others like adopting distinctive hairstyles.
