March 11 marks Commonwealth Day, and Duchess Meghan along with other members of the British royal family were out in full force to celebrate the special day.
As Prince Harry is the President of the Queen's Commonwealth Trust, he and the Duchess of Sussex began their day at a special event hosted at Canada House in London, where the couple joined young Canadians to celebrate the diverse community of Canadians living in the UK.
Meghan herself has close ties to the country as she spent many years living in Toronto when she was filming the television series Suits, where she played paralegal Rachel Zane.
The royal parents-to-be met with young Canadians working in fashion, the arts, business and academia and watched a demonstration of the spring tradition of making maple taffy.
Just weeks away from giving birth to her first child, Meghan looked absolutely radiant in a bespoke green Erdem coat and dress, complete with beaded embellishments, accessorising with black Aquazzura heels and a matching clutch by Givenchy.
The outfit was the perfect way to honour both the UK and Canada, as the fashion designer Erdem Moralioglu was born in Canada to an English mother and spent much of his childhood between England and Montreal.
And as if it couldn't be sweet enough, according to People, Erdem have revealed the black floral embellishments are known as the "Doria beaded rose embroidery," a cute connection to Meghan's mother, Doria Ragland.
Following their appearance at Canada House, Meghan and Harry made their way to Westminster Abbey to join the rest of the royal family for the annual Commonwealth Day Service.
While the family mark the day every year, this year is particularly special as it is the 70th anniversary of the institution.
It's the largest inter-faith gathering in the UK but despite the formalities, the Commonwealth Day service featured musical performances by British band Clean Bandit and tenor, Alfie Boe, who sang an acapella version of Snow Patrol's Run.
Heavily pregnant Meghan, 37, made an outfit change for her arrival with Prince Harry, opting for a white and black printed dress from Victoria Beckham's AW19 Collection, which she paired with a pristine cream coat and matching pillbox hat.
Arriving separately with Prince William, Meghan's sister-in-law, Duchess Kate, greeted her with a kiss on the cheek.
While Prince William and Duchess Catherine appeared poised and formal, parents-to-be Prince Harry and Duchess Meghan beamed with the latter even sharing a joke with her father-in-law Prince Charles as they waited for the Queen to arrive.
Kate wowed in a beautiful red Catherine Walker coat dress with a matching fascinator, which she also wore when she touched down in New Zealand during a royal tour in 2014.
The Queen, dressed in a regal purple, led the royal family in the celebration, which was also attended by Prince Charles and Duchess Camilla and the Queen's second son, Prince Andrew.
