There are many age-old traditions the royal family must follow, including strict rules on the clothes they have to wear to formal events. One extremely important accessory is a headpiece, and royal women - including Kate Middleton and Meghan Markle - are often seen wearing hats at christenings, birthdays and weddings.
The royal ladies will be expected to wear either a hat or fascinator as they attend the Queen's funeral on Monday 19 September, to pay their respects to the late monarch and honour the longstanding tradition. Queen Consort Camilla and the Duchesses of Cambridge and Sussex, alongside all other royal women, will wear black dresses and black tights with a traditional hat and lace black veil in some form.
