Meanwhile, the Duchess of Sussex paid her respects from a separate balcony with Sophie, Countess of Wessex.
The former Suits star chose a bespoke Stella McCartney coat for the event with a Stephen Jones wide-brimmed hat to finish.
Prince Harry and Prince William laid wreaths during the memorial alongside Prince Andrew, Prince Edward and Princess Anne.
Though the royal family's position during the event has nothing to do with regal protocol.
After last year's ceremony, where Meghan stood alongside Elke Büdenbender, the wife of the German president, royal expert Richard Fitzwilliam told The Sun: "The balconies overlooking Whitehall occupied by the Royal Family are very small."
"The Queen was without Prince Philip who has retired and the Duchess of Cornwall and the Duchess of Cambridge are future Queen Consorts."
The evening before, the royal family stepped out for the annual Festival of Remembrance Service at the Royal Albert Hall.
The Duchess of Cambridge chose a navy ensemble by go-to designer Emilia Wickstead finished with Jessica McCormack earrings and a surprisingly affordable Zara headband.
Her sister-in-law also put her best fashion foot forward in an Erdem brocade dress finished with Jessica McCormack ruby heart-shaped earrings her favourite $1158.95 Aquazurra bow-back shoes.
It's the first time the Cambridges and Sussexes have been photographed in public together since Prince Harry seemingly confirmed rumours of a rift between himself and Prince William.
