狂热

   一种时尚突然在一个小群体小流行开来，然后又很快消失，称为狂热。  它的出现通常是由于某些非常夸张的特征或细节的引入，激发了消费者的兴趣。这种狂热很快蔓延起来，被人们模仿。狂热的时尚通常是在低价位服装中开始，复制起来相对容易，然后在短时间内充斥市场。由于市场的饱和，公众又很快喜新厌旧，它也很快地消失在人们的视野里。数十年来，我们曾有过“朋克”发型狂热、“都市牛仔”狂热和“吉拉吉”狂热。

Fad

A fashion that suddenly sweeps into popularity, affecting a limited part of the total pop- ulation, and then quickly disappears is called a fad. It comes into existence by the in- troduction of some feature or detail, usually exaggerated, that excites the interest of the customer. The fad starts by being quickly accepted and then quickly imitated by others.
Fads often begin in lower-price ranges, are relatively easy to copy, and therefore flood the market in a very short time. Because of this kind of market saturation the public tires of fads quickly and they end abruptly. In recent decades we have had the "punk" hairdo fad, the Urban Cowboy" fad and the grunge fad.
