For example, wearing expensive clothes can communicate wealth, the image of wealth, or cheaper access to quality clothing. All factors apply inversely to the wearing of inexpensive clothing and similar goods.The observer sees the resultant, expensive clothes, but may incorrectly perceive the extent to which these factors apply to the person observed. (cf. conspicuous consumption). Clothing can convey a social message, even if none is intended.

If the receiver's code of interpretation differs from the sender's code of communication, misinterpretation follows.

In every culture, current fashion governs the manner of consciously constructing, assembling, and wearing clothing to convey a social message. The rate of change of fashion varies, and so modifies the style in wearing clothes and its accessories within months or days, especially in small social groups or in communications media-influenced modern societies. More extensive changes, requiring more time, money, and effort to effect, may span generations. When fashion changes, the messages communicated by clothing change.

Europe

In the Middle Ages the European nobility used a dress code to differentiate themselves from the other classes.

The Americas

The indigenous peoples of the Pacific Northwest Coast had a complex social structure, including slaves, commoners, and nobles, and dress codes to indicate these social distinctions. John R. Jewitt, an Englishman who wrote a memoir about his years as a captive of the Nootka people in 1802-1805, describes how, after some time living there, Maquina and the chiefs decided that he must now be "considered one of them, and conform to their customs". Jewitt resented the imposition of this dress code, finding the loose untailored garments very cold, and attributed to them a subsequent illness of which he almost died. He was not allowed to cut his hair, and had to paint his face and body as a Nootka would.

Signifier

Gender

Various traditions suggests that certain items of clothing intrinsically suit different gender roles. In particular, the wearing of skirts and trousers has given rise to common phrases expressing implied restrictions in use and disapproval of offending behaviour. For example, ancient Greeks often considered the wearing of trousers by Persian men as a sign of effeminacy.Fact: date=February 2007

Social status

In many societies, people of high rank reserve special items of clothing or decoration for themselves as symbols of their social status. In ancient times, only Roman senators could wear garments dyed with Tyrian purple; only high-ranking Hawaiian chiefs could wear feather cloaks and palaoa or carved whale teeth. In China before the establishment of the republic, only the emperor could wear yellow. In many cases throughout history, there have been elaborate systems of sumptuary laws regulating who could wear what. In other societies (including most modern societies), no laws prohibit lower-status people from wearing high-status garments, but the high cost of status garments effectively limits purchase and display. In current Western society, only the rich can afford haute couture. The threat of social ostracism may also limit garment choice.
