Today, people in rich countries are linked to people in poor countries through the commoditization and consumption of what is called fashion. People work long hours in one area of the globe to produce things that people in another part of the globe are anxious to consume. An example of this is the chain of production and consumption of Nike shoes, which are produced in Taiwan and then purchased in North America. At the production end, there is nation-building a hard working ideology that leads people to produce and entices people to consume with a vast amount of goods for the offering[clarification needed]. Commodities are no longer just utilitarian but are fashionable, be they running shoes or sweat suits.

The beginning in Europe of continual and increasingly rapid change in clothing styles can be fairly reliably dated. Historians, including James Laver and Fernand Braudel, date the start of Western fashion in clothing to the middle of the 14th century, though they tend to rely heavily on contemporary imagery and illuminated manuscripts were not common before the fourteenth century. The most dramatic early change in fashion was a sudden drastic shortening and tightening of the male over-garment from calf-length to barely covering the buttocks, sometimes accompanied with stuffing in the chest to make it look bigger.
The best way to understand the consumers' needs and therefore predict fashion trends is through market research. There are two research methods: primary and secondary. Secondary methods are taking other information that has already been collected, for example using a book or an article for research. Primary research is collecting data through surveys, interviews, observation, and/or focus groups.
Early Western travelers, traveling whether to India, Persia, Turkey or China, would frequently remark on the absence of change in fashion in those countries. The Japanese shōgun's secretary bragged (not completely accurately) to a Spanish visitor in 1609 that Japanese clothing had not changed in over a thousand years. However, there is considerable evidence in Ming China of rapidly changing fashions in Chinese clothing. Changes in costume often took place at times of economic or social change, as occurred in ancient Rome and the medieval Caliphate, followed by a long period without major changes. In 8th-century Moorish Spain, the musician Ziryab introduced to Córdoba[unreliable source] sophisticated clothing-styles based on seasonal and daily fashions from his native Baghdad, modified by his own inspiration. Similar changes in fashion occurred in the 11th century in the Middle East following the arrival of the Turks, who introduced clothing styles from Central Asia and the Far East.
