After having a luncheon with the King and Queen at the Royal Palace, The Duke & Duchess made their way down the streets of Stockholm.

Crown Princess Victoria and Prince Daniel accompanied them from the Palace to the nearby Nobel Museum. On the way, the royal couples had the chance to meet the public who had assembled in Stortorget, the oldest square in Stockholm.

It is the first time the two couples have caught up publicly since Victoria and Daniel attended William and Kate's wedding in 2011.

The two couples are sort of each other’s counterparts in their respective countries. One day, William will be King, and Victoria will be Queen. William and Kate are 35 and 36, respectively, while Victoria is 40 and Daniel is 44. The Swedish couple also have two children of a similar age: Princess Estelle, 6, and Prince Oscar, 2.

Inside the museum, the couple met a number of Nobel Laureates, and heard more from the Museum's curator about Science in Sweden and the Nobel Laureate system.

William and Kate then traveled to ArkDes, Sweden’s national centre for architecture and design. There they attended an event celebrating architectural collaboration and the best of Swedish design, from the most iconic and global furniture brands, to up-and-coming homeware designers with new takes on sustainable furnishings.

The met with the head of the IKEA company design, Marcus Engman, revealing to him that they have some IKEA pieces in the children's rooms at home.

For her second outfit of the day, The Duchess changed into a matching dress and coat by one of her favourite quintessential English labels, Catherine Walker.

Both the forest green dress and coat are custom-made pieces; that is, they are based off of already existing pieces in the Catherine Walker collection, rather than completely made for Kate from scratch (bespoke). From looking through the collection, there are many similarities with Kate's dress and the 'Bea' dress in terms of the funnel neck, saddle shoulder and crepe fabric, however Kate's is more of a shift dress to accommodate her bump.

Her coat, another custom-made Catherine Walker piece, features asymmetric buttons, an A-line silhouette and sits mid-calf.

Kate paired the coat with a Troy London 'Faux Fur Lapel Collar in Black', available for £65/$90, and matching 'Faux Fur Cuffs in Black', available for £40/$56. The company was set up by her friend Rosie Van Cutsem.

As for her hat, you may recognise it as being the same Peruvian Connection 'Vallnord Alpaca Fur Hat' she wore on Christmas Day last year. The £70/$99 hat is sustainably made from fur gathered from natural stock loss in the bitter Peruvian winters.

Kate was carrying a little handbag which we don't often see! This was Mulberry's 'Mini Seaton' style which was £895/$1,150 before selling out.

During lunch, Kate wore her trusty black suede Tod's pumps with a block heel, before swapping them for her Russell & Bromley Half N Half boots when going outside (available still for $635). Kate brought back out her Kiki McDonough Special Edition Green Tourmaline, Green Amethyst and Diamond Earrings which were especially made to celebrate Charlotte's birth in 2015.Ambassador!
