The Prince and Princess of Wales joined King Charles III, Queen Camilla and other working royals at Buckingham Palace on Saturday afternoon for a Governors-General reception.
These representatives of the monarch from across the Commonwealth Realms have arrived in London to attend Queen Elizabeth II's State Funeral on Monday.
Kate wore an Emilia Wickstead midi dress - the 'Jorgie' style in black crepe.
The Princess accessorized with a three-strand pearl necklace which palace aides confirmed belonged to the late Queen. It appears to be the same one she wore to receive Her Majesty's coffin at Buckingham Palace. Queen Elizabeth II had a vast collection of three-strand pearl necklaces which Queen's Jewel Vault covers in more detail.
Kate also wore Her Majesty's pearl and diamond "Silver Jubilee" earrings which were originally loaned to the Duchess in 2016.
On Kate's right wrist was Princess Diana's Nigel Milne 3-Strand Pearl Bracelet.
On her feet were her trusty Gianvito Rossi 105 pumps in black suede.
The Prince and Princess of Wales visited Army Training Centre Pirbright on Friday to meet with troops from the Commonwealth who have been deployed to the UK to take part in the state funeral of Her Majesty Queen Elizabeth II.
Soldiers from Canada, Australia and New Zealand have gathered at Pirbright to rehearse their roles in the ceremony.
William and Kate met senior representatives of the defence staff and servicepeople from each nation to thank them all for the part they are playing in marking the death of the Queen.
The princess looked dignified wearing her black Catherine Walker military-inspired midi coat.
Thanks to Ann who left a comment reminding me she first wore the piece for the Remembrance Sunday service in 2020. For today's outing, Kate had the tassels removed from the epaulettes.
She paired the coat with her black Lock & Co 'Abney' Hat.
Kate debuted the Russell & Bromley '100Point' blade heel pumps, and carried her black Mulberry 'Amberley' handbag.
The princess honored the late Queen by wearing Her Majesty's pearl and diamond "Silver Jubilee" earrings which were originally loaned to Kate in 2016.
The Prince and Princess of Wales visited Sandringham House this afternoon to view the floral tributes left at Norwich Gates for the late Queen.
William and Kate stopped to read some of the tributes.
The Prince and Princess then went on a walkabout to greet the public that had gathered outside of the Sandringham Estate.
Kate wore a long black coat over a black midi dress featuring a ribbed bodice and pleated skirt.
The silhouette of the coat appears to be identical to the navy Catherine Walker long wool coat the Duchess first wore in May 2021.
Here's a closer look at the mixed-media dress.
It appears to be a modified Alexander McQueen piece. The ready-to-wear version has a the same ribbed bodice, stitched waist and pleated skirt. Kate had the crisscross detail removed from the waist. Thanks to UFO No More for the ID.
Kate carried her Grace Han 'Love Letter' Small Top Handle Bag, and on her feet were her Gianvito Rossi 105 pumps in black suede.
The Princess honored the late Queen by wearing the pearl and diamond earrings which were originally loaned to Kate from Her Majesty in 2016. She also wore a cross pendant necklace.
The Sandringham Estate in Norfolk is a royal residence owned personally by the monarch. Queen Elizabeth II would customarily spend the anniversary of her father's death with her family at Sandringham House. More recently, she used it as her official base from Christmas until February. Below is a photo of Her Majesty's last public engagement at Sandringham House where she marked her Platinum Jubilee.
This afternoon, Queen Elizabeth II left Buckingham Palace for the last time. Her Majesty's coffin was transported on a Gun Carriage of The King's Troop Royal Horse Artillery from Buckingham Palace to Westminster Hall where she will lay-in-state until the early morning of her funeral.
The somber procession down The Mall was led by her children, King Charles III, Princess Royal, Duke of York and Earl of Wessex, her grandchildren the Prince of Wales, Duke of Sussex and Peter Philips, and other senior royals.
The Princess of Wales followed the procession in a car alongside the Queen Consort.
The Princess joined her husband's side inside Westminster Hall where senior royals stood in formation facing the coffin on its catafalque.
Dressed in a black Catherine Walker coat, Kate curtseyed the Queen's coffin before departing from Westminster Hall at the end of the service.
The Princess accessorized with pearl jewelry. Royal women often wear pearls when in mourning - a tradition that can be traced back to Queen Victoria. Kate wore the Collingwood pearl drop earrings, and she honored the late Queen by donning the Diamond and Pearl Leaf brooch which belonged to Her Majesty.
Kate first borrowed the piece during a trip to Belgium for the 100th anniversary of the Battle of Passchendaele.
Below is a photo of Queen Elizabeth II wearing the brooch in 1999 during a State Visit to South Korea.
Kate's hat appears to be the Jane Taylor Pillbox Halo in black with a birdcage veil.
The Prince and Princess of Wales will travel to Norfolk tomorrow to view flowers for the Queen left by well-wishers at her former home Sandringham’s Norwich Gates.
The Prince and Princess of Wales made their first joint public appearance since the passing of Queen Elizabeth II, who died at Balmoral Castle on 8 September, 2022.
William and Catherine invited the Duke and Duchess of Sussex to join them to view the flowers and greet well-wishers who had gathered on the Long Walk at Windsor Castle to pay tribute to Her Majesty.
Below is a collection of photos of Catherine greeting the public and viewing the flowers.
For today's walkabout, Princess Kate wore a simple black sheath dress with velvet trim details.
Gabi on Twitter points out that the design is identical to the blue Jenny Packham dress she wore during a visit to Ballymena in 2019.
It appears she wore her Gianvito Rossi 'Gianvito 105' pumps in black suede.
The princess completed the sombre ensemble with her beloved Annoushka Pearl and Kiki Diamond Hoop Earrings.
Yesterday, Kate was spotted driving in Windsor wearing a black Cefinn 'Eva' Blouson Sleeve Fit and Flare Merino Knit Dress as identified by @foundbybojana.
The £280 rib-knit dress features a funnel neck, blouson sleeves and a flared skirt.
