Like skinny jeans, side parts and ankle socks, leggings are the latest trend caught in the generational crosshairs between Millennials and Gen Z.
According to some members of the latter generation on TikTok, leggings - specifically the plain black, full length kind - are yesterday's news, and a telltale sign of one's age.
In July, trade publication The Business of Fashion declared "the reign of leggings is over", writing, "Millennials helped crown leggings as the ultimate do-everything uniform, Gen Z is shifting the silhouette entirely, gravitating toward oversized, slouchier workout clothes".
While globally, Google search data since 2016 shows the style's popularity has declined, in Australia, that trend seems to be less acute.
