The TikTok Trends 2025 (and those to come) are characterised by this extreme transience, raising questions about consumption, creativity and sustainability.

In this article, we will dive into the heart of this stylistic whirlwind. We will analyse how the micro-trend cycle works in TikTok, look back at some recent examples and discuss whether it is possible – or even desirable – to try to keep up with this ephemeral fad.

The Algorithm as Stylist: How does the TikTok Fashion Cycle Work?

TikTok is not just a social network; it has become one of the biggest drivers of fashion trends on the planet. Several factors contribute to this hyper-accelerated cycle:

• The Power of the TikTok Algorithm: Its recommendation system is incredibly effective at identifying content that generates engagement (likes, comments, shares, viewing time) and amplifying it massively in a short time. A look or an outfit can go viral overnight.
• (Apparent) Democratisation: Any user, not just big brands or established influencers, has the potential to start a trend with a creative video.
• Visual and Imitative Format: Short, often musical and aesthetically focused videos facilitate quick imitation of looks and styles. The format “Get Ready With Me” (GRWM) or the “outfit checks” are breeding grounds for this.
• Viral Sounds: Often, micro-trends are associated with specific songs or audios, which helps to group content and quickly identify aesthetics.

• Past Example: #CoastalCowgirl (adapted): It mixed elements of the West (cowboy boots, denim) with a relaxed beach aesthetic (flowing fabrics, light tones).
