The dress, which Kate first wore to Meghan Markle and Prince Harry's wedding rehearsal, was a quiet nod to Princess Diana, who wore a very similar floral dress in 1992 to visit a friend at St. Mary's Hospital - you can see the image here. Of course, this isn't the first time Kate has used fashion to pay tribute to her late mother-in-law, the royal often wears Diana's own jewellery and accessories and opts for designers Diana favoured.
But Kate wasn't the only one to consider her look for the momentous day: Princess Charlotte added a personal touch to her outfit with the addition of a sequined unicorn keychain on her school bag.
Another royal fashionista in the making? We'd say yes.
