Throughout the world, clothing has many uses. It is used to provide protection from the elements. It is also worn to prevent others from seeing specific parts of one's body. However, the parts of the body that must be covered vary widely throughout the world. Some clothing is worn to

provide supernatural protection. Wearing a lucky shirt to take an exam is calling for supernatural assistance.

People in all cultures use clothing and other forms of bodily decoration to communicate status,intentions and other messages. In North America, we dress differently for business and various leisure activities. North American women usually are much more knowledgeable of and concerned

With little difference in messages communicated by clothes than men. At times, this leads to silly mistakes of interpretation(解释) of female intentions on the part of men. Of course. clothing styles also are intended to communicate messages to members of the same gender(性别).

Long before we are near enouth to talk to someone, their appearance tells their gender, age,economic class. and often even intentions. We begin to recognize the important cultural clues at an early age. The vocabulary of dress that we learn includes not only items of clothing but also

hairstyles, jewelry, and other body decoration. In most cultures, however, the same style of dress communicates different messages depending on the age, gender. and physical appearance of the individual wearing it.

Putting on certain types of clothing can change your behavior and the behavior of others towards you. This can be the case with a doctor's white lab coat, or an army uniform. Most uniforms are clearly symbolic so that they can rapidly and unmistakably communicate status. For instance. the

strange hairstyle and clothing of the English "punks" are essential aspects of their uniforms.

There are many forms of body decoration other than clothes that are used around the world to send messages. These include body and hair paint, and even body deformation. When doctors put braces on teeth, they are actually doing the same thing - deforming or reforming a part of the body

to make it more attractive.
