What is the term for styles that are only popular for a short time?

Fads are defined as styles or behaviors that become extremely popular in a very short period but fade just as quickly. They capture the public's interest momentarily, often characterized by their novelty and excitement. Fads can span various domains, including fashion, entertainment, and even diet. For instance, a specific clothing item or accessory may become trendy for a season but is often forgotten shortly thereafter.

Classics refer to timeless styles that remain popular over many years, while timeless suggests an enduring relevance and appeal that transcends short-lived popularity. Trends, on the other hand, can last longer than fads and may evolve into something more sustained in popularity. However, the key difference is that fads are fleeting, often lacking the lasting influence found in trends or classics.
