Karan Johar has arguably done for Bollywood fashion what a good stylist does for a star. He gave it an edge and personality. Johar's cinema became a visual mood board for aspirational India from the late '90s. Fans were convinced that his movies would serve the right dosages of style and teach them a thing or two about trends. Instagram and Tiktok, who? With Kuch Kuch Hota Hai, he turned friendship bands, logo sweatshirts and sporty chic into a nationwide obsession. Kajol's tomboy-to-saree transformation was a masterclass in how femininity could be styled on screen.
