If you've noticed a surge of metallic fabrics, vibrant colors, and bedazzled accessories on your TikTok feed, you're witnessing the unmistakable comeback of Y2K fashion. This nostalgic revival has been embraced by Gen Z, who are putting their own contemporary spin on the low-rise jeans and baby tees that defined the early 2000s. Major fashion houses have also jumped on the trend, incorporating Y2K elements into their runway collections and collaborating with brands that were iconic during that era.
