She will also have to pack a black outfit in her bag, as is customary for all royals according to the expert.
Daena noted: “While the Queen favours bold colours and prescribes them to her family because royals are meant to be easily distinguishable in a crowd, a tragedy delivered a life lesson, giving rise to a whole new protocol that applies to this date.
“When Queen Elizabeth’s flight landed in England on the death of her father, her dresser realised they hadn’t packed a black mourning outfit for the new mourning Queen to be received by her ministers.
“Ever since then, Royal Family members have to compulsorily pack a black outfit when travelling.”
Meghan famously broke royal protocol when at the British Fashion Awards when pregnant in 2018. She wore dark nail varnish when according to this expert, the Queen only approves clear or nude nail varnish.
