Diana gradually became a style icon who shaped fashion. This began with her famous wedding dress, designed by David and Elizabeth Emanuel, which boasted a 25-foot train and 153-yard veil. Over the subsequent decades Diana's fashion constantly evolved, from her spontaneous yet influential '90s pixie cut to becoming synonymous with the tiara. Her most infamous outfit was 'the revenge dress', a black off-the-shoulders dress designed by Christina Stambolian. Diana wore it the same night Prince Charles confessed to adultery on television.
