The Cambridge family bade farewell to Poland this morning, and boarded a private jet bound for Berlin to begin the German element of the royal tour.
The Duchess wore a bespoke cornflower blue coat by British designer, Catherine Walker. The choice of colour was a nod to Germany where the cornflower is the country's national flower.
The design of the coat is very much like the red Catherine Walker number she wore during the Canadian royal tour in 2011.
Under the coat, Kate wore a tonal blue lace dress with a scalloped hem.
She carried a new clutch bag.
It is theJimmy Choo 'Vivien' clam satin clutch (US$995) - ID by @Perthsfashion. The body is softly gathered and embellished with Swarovski-studded hardware alongside a pale-gold tone metal base chain.
The bag is not available in Kate's colourway but is in stock in Black and Vintage Rose at Selfridges. It is also available in black from Neiman Marcus and Far Fetch.
On her feet were the Gianvito Rossi 'Gianvito 105' Praline Suede Pumps.
Kate accessorized with her KIKI Blue Topaz and Diamond Drop Earrings, and today she added the coordinating KIKI Eden Blue Topaz Flower Necklace (£1,167). The new piece features a blue topaz flower surrounded by pave set diamonds in 18ct white gold.
Kate completed the ensemble with her trusty Cartier Ballon Bleu Stainless Steel Bracelet Watch.
A closer look at Kate's glamorous up-do.
William and Kate's first engagement in Germany was a private meeting with Chancellor Angela Merkel.
Following this the Duke and Duchess visited the Brandenburg Gate - Berlin’s most famous landmark and a symbol of German unification.
The Royal couple greeted the crowds that had gathered on Pariser Platz in front of the Gate, before making their way to the Holocaust Memorial.
Here they toured the museum before walking through the Field of Stelae.
In the afternoon, the Duke and Duchess travelled to the eastern district of Marzahn. They visited Strassenkinder, a charity which supports young people from disadvantaged backgrounds.
The Royal couple will then return to the west of the city, and meet with President Steinmeier at the Bellevue Palace for afternoon tea.
The Duke and Duchess of Cambridge concluded their first day in Germany with the Queen's Birthday Party at the Ambassador's residence in Berlin.
As anticipated, Kate made a wardrobe change. She arrived for the party in a red off-the-shoulder dress by Alexander McQueen (£2,075) - ID by @RegalRepliKate on Twitter.
The floor-length gown with ruffled hem is from McQueen's Spring '17 collection. Its inspiration comes from the beautiful landscapes and folkloric history of the Shetland Islands. Crafted from cotton and silk-blend chiffon with a crinkled finish, this vivid red dress is shirred along the off-the-shoulder neckline and waist.
The dress is also available in pink at StyleBop where it is reduced to €831.
Kate debuted a pair of red Simone Rocha crystal earrings (£195) - ID by @heavenQRF on Twitter.
Kate’s earrings are sold out in red, but they’re still available in black and transparent perspex. Simone Rocha also offers a similar design in red:
On her feet were a new pair of taupe suede sandals with scalloped straps.
They are likely to be one of these styles by Prada.
ID UPDATE (20 Jul 2017)
The Duchess stepped out in the shoes again on her final night in Germany and we can clearly see they are the ankle strap pair.
And that concludes day three!
