Royal women are expected to dress conservatively, respecting well-established dress codes for both formal and daywear. Modern princesses, however, have thrown out the typical playbook to dress more practically. From Queen Elizabeth and Princess Anne to Princess Diana and Kate Middleton, we look at the British royal dress codes that are still followed – and those that are not. 10 royal rules to follow when dining with Queen Elizabeth Royal protocol for women’s fashion includes no revealing cuts, no wearing black outside of funerals, no bare knees and no heavy make-up – a more natural look is preferable.
