The Duke and Duchess of Sussex dazzled London last night in what was likely to be Harry's final outing in his Royal Navy uniform on behalf of the Crown.
Meghan Markle painted the town red as she matched her vivid gown to her prince's uniform as they arrived to attend the annual Mountbatten Festival of Music at the Royal Albert Hall in South Kensington.
The couple received a long round of applause and a standing ovation as they took their seats in the royal box as Harry appeared in his full Captain General uniform for what could be the last time.
The Duke of Sussex, who served in Afghanistan, was made Captain General of the elite corps last year, replacing his grandfather Prince Philip.
While Harry will be entitled to a small Army Pension in future as a retired officer, he is understood to be likely to lose the key role as head of the Royal Marines once he and Meghan begin their new life outside the royal family.
Meghan is wearing what appears to be a gown from luxury Mayfair atelier Safiyaa.
Her stunning gown appears to be one from the British fashion house's collection, the Kalika Long Dress, which costs Sh173, 380 (£1,295) online.
Meghan's striking red shoes are by Italian luxury brand Aquazurra, her matching clutch is by Spanish fashion designer Manolo Blahnik, and earrings by Irish designer Simone Rocha.
It is the second time the couple have colour coordinated as they made their glamorous final outings in London as part of their tour before they step aside from royal life.
Meghan glowed in a blue Victoria Beckham dress and midnight blue pumps, matching her husband's navy suit and blue tie as the beaming couple displayed a united front in London earlier this week.
The happy couple were pictured grinning at each other as they walked through the rain under an umbrella to attend the 2020 Endeavour Awards.
Last night’s public outing for the Royal Marines Charity event is a milestone final appearance for Harry.
He is attending his final annual performance of the Massed Bands of Her Royal Majesty's Royal Marines as a member of the Crown.
The event last night marks the 75th anniversary of the end of the Second World War and the 80th anniversary of the formation of Britain's Commandoes.
It was being held to fundraise for the Royal Marines Charity and CLIC Sargent.
They took their seats in the royal box, having been greeted by five members of the Royal Marines when they arrived at the venue in South Kensington.
Harry and Meghan turned heads this week as they made their first big public appearance in Britain since beginning the first phase of their new life with son baby Archie in Canada, amid the royal split.
Last evening's event was one of their last big engagements before their shift to a new life begins.
The awards recognise wounded, sick or injured military personnel who turn to sport or adventure as part of their recovery.
But last night’s is not quite the couple's final engagement as a part of the royal family.
The pair are set to appear in public alongside the Queen for the first time since they dropped their bombshell announcement they planned to step aside from royal life on Monday.
The Sussexes will appear alongside Harry's grandmother, his father Prince Charles, along with Camilla Parker-Bowles, and Prince William and Kate Middleton at the Westminster Abbey royal engagement before they walk away from royal life.
Harry and Meghan will appear with the senior members of the royal family for the first time since their January 'Megxit' announcement, in order to mark Monday's Commonwealth Day service.
