Say goodbye to the “20-year” fashion rule; TikTok dictates the trends now. As fashion rules / styles continue to evolve in the TikTok-era, the so-called “20-year-rule” is becoming less relevant in defining how trends cycle through the pipeline. Since TikTok took off, we’ve seen young people bring back fashion from the ‘60s, ‘70s, ‘80s, ‘90s, 2000s, and 2010s, while popularizing micro-trends like Dark Academia, Tumblrcore, Cottagecore. And when people are “done” with a trend—no matter how old or simple it may be—all it takes is one made up word and a viral TikTok post to deem it “out of style”—as seen through the rise of “cheugy” and the cancellation of side parts and skinny jeans. When it comes to specific products taking off on TikTok, anything from apparel, to skincare, and books can go viral in an instant—so long as it fits the algorithm. According to data from Stitch Fix, TikTok trends directly affect the items clients request from them, while requests mentioning TikTok increased 75% in the past year. TikTok is the new style guide, taking on the role of fashion stylist, trend curator, and more for Gen Z and Millennials. (In The Know)
