According to fashion blog The Trend Spotter, the kidcore aesthetic centers around 1990s pop culture, though some pieces are taken from the early 2000s. Taking inspiration from childhood pop culture, it remembers and embellishes the aesthetics, fashion, and characters of that time period. Mismatched pieces and prints are embraced and encouraged, whereas neutral colors don't even have a look-in. It's all about pops of color and harking back to the freedom of childhood. 

It isn't just online — celebs have been spotted sporting kidcore too. A notable sub-genre of kidcore is "Hobicore" (via Nylon), a name taken from BTS member and general K-pop superstar J-Hope, a.k.a. "Hobi." J-Hope has long championed outfits that can be categorized as kidcore and has inspired many fans to embody a similar look. Harry Styles has also leaned into kidcore now and again, with the most obvious example being the JW Anderson cardigan he wore. The rainbow mismatched print cardigan very quickly went viral, spawning a whole lot of crochet attempts (via Stylist).
