Princess Olympia of Greece, seen here rocking head-to-toe Balmain, never lets us down when it comes to cool style. The young royal certainly takes fashion seriously: she's a student at New York City's Parsons School of Design and in 2016 became a face for Michael Kors. Photo: Getty Images

Queen Elizabeth's late sister Princess Margaret, seen here in sequins and fur in 1951, was a true trendsetter in her heyday. Curator of the Fashion Rules exhibition at Kensington Palace Cassie Davies-Strodder told Grazia: "Margaret was a distinctive fashion icon because she was so glamorous – with all the beauty of a Hollywood film star, she brought a new kind of style of the Royal Family." Princess Margaret's style has been rediscovered by a new generation thanks to her oh-so-cool character on Netflix series The Crown. Photo: Getty Images

We've heard about the Kate Effect and the George Effect – and royal toddler Princess Charlotte shows that she, too, has inherited the magic touch when it comes to fashion.
