Fashion is an area of trends and the prevailing styles that influence culture, society and individuality. Fashion is a multifaceted concept that can be expressed through clothing, footwear, accessories, and even behaviours. The most common definition of fashion is that it is a style or trend in dressing that a large segment of the population follows during a certain period of time. It also includes a social movement that can be reflected through cultural or artistic expressions like art, movies, music, etc.

A new fashion often begins with the spread of a particular item from another country or region. This can be an ethnic garment that a popular designer adopts from another culture or community, or it can be a form of adornment like jewelry or tattoos. Once a new adornment becomes fashionable, it usually stays fashionable for a while until another type of adornment replaces it. This cycle often repeats itself over the course of 20 years – that same style that was once in fashion will soon be out of fashion.

As a result of globalization, the lines between what is considered fashionable and what is not, can become blurred. For example, elements of ethnic dress might be incorporated into mainstream fashion trends by the actions of a business person that promotes and exploits the fad for profit.

In addition to societal and business influences, the choice of Fashion is largely determined by celebrities, musicians and athletes. For example, hoodies became popular due to rap musicians and many youngsters try to emulate the style of their favorite music star.
