With William by her side, Kate was all smiles as she headed into Westminster Abbey to mark the annual Commonwealth Day celebrations alongside other senior members of the Royal Family.
The Queen, the Duke of Edinburgh, the Prince of Wales and Duchess of Cornwall were all in attendance.
The Commonwealth Day Service is held on the second Monday of March and it celebrates the richness of the Commonwealth. It is the biggest multi-faith celebration in the UK, which has 53 member countries.
Organized by the Royal Commonwealth Society, the Commonwealth Day Observance service is an hour-long service attended by a mixture of Royals, politicians, High Commissioners, Commonwealth dignitaries, and more than 1,000 children.
This was a first for William and Kate as they had never before attended the service at the Abbey.
The Duke and Duchess of Cambridge, who arrived first, chatted with Charles and Camilla as they waited for Prince Philip and the Queen.
Next, the royal party was introduced to a line-up including Mr Sirisena and his first lady, plus Commonwealth secretary-general Kamalesh Sharma and senior Abbey clergy.
They then joined a procession that included a group of Brownies, down the nave of the historic ecclesiastic building before the Queen’s Commonwealth Day message was played via giant screens.
Upon the completion of the ceremony, a procession of the flags of all the Commonwealth states led the royals and dignitaries from the Abbey where the Queen, the Duchess of Cornwall, and Kate were presented with flowers.
She first donned the coat for Trooping the Colour back in 2013.
The gorgeous coat features a wide collar, side darting, three-quarter sleeves and oversized pearl buttons. Unfortunately, the bespoke coat isn’t available to buy.
Kate paired her spring-ready coat with a matching Jane Taylor fascinator in a natural nude hue, her pink satin Prada ‘Raso’clutch and her pink satin Prada court heels in a similarly chic shade.
She wore a pair of new earrings by Kiki McDonough. They are the Kiki Classic Morganite and Diamond Cushion Drop Earrings (£3,400 and currently sold out). It looks like Kate may have paired the drops with the Kiki Classic 18ct White Gold and Diamond Hoops (thanks to ‘My Small Obsessions’ on FB).
Lastly, the Duchess opted for a glamorous half-up, half-down style with the rest of her hair loose around her shoulders in tumbling curls.
