Award-winning producer Nick Bullen, of True Royalty TV, speaks to Kate Thornton in episode 12 of Yahoo UK's video series 'The Royal Box'.
Contrary to popular belief, women of the royal family don't have a certain dress code they must adhere to. Nude tights for all formal engagements and neutral nail varnish only are two such 'rules' that have done the rounds in recent years. There's even one theory that every female member of the royal family wears the exact same Essie shade. But no such rules exist, royal biographer and Majesty magazine editor-in-chief Ingrid Seward tells Yahoo UK during episode two of 'The Royal Box.' Watch the full episode on yahoo.co.uk from Friday 22 June.
