In this programme we meet a wide variety of fashion experts, industry insiders and royal journalists who spend their working lives tracking every move of the women of the House of Windsor. We meet those responsible for Princess Diana’s style transformation and the Duchess of Sussex’s fashion-forward look. We unravel the coded messages in the world’s most iconic wardrobes and reveal the meaning behind the world’s most famous wedding dresses, from Diana’s oversized romantic fairy-tale gown to Meghan’s sleek and glamorous column of silk.
