How long do trends last?

Trends can vary widely in duration, lasting anywhere from a few weeks to several years, depending on factors like cultural relevance, consumer interest, and technological advancements. Some trends, particularly in fashion or social media, may be fleeting, while others can evolve and become more established over time. Additionally, trends often experience cycles of resurgence, where past trends re-emerge in new forms. Ultimately, the lifespan of a trend is influenced by its adaptability and the context in which it exists.
