Kate wore a green suit for a meeting with Norwegian royalty at Windsor Castle.

The two couples engaged in a productive discussion about green energy, the environment, and more.

The Norwegian royals visited the UK to foster economic cooperation and strengthen cooperation in the energy sector.

Literature was a focus for Princess Mette-Marit, who has spent years promoting literature among younger people.

The visit honored Norway's historical links to Great Britain and strengthened royal relations.

Haakon is heir apparent to the throne of Norway, and his father is a second cousin of the late Queen Elizabeth.

William and Kate last met with Haakon and Mette-Marit during their official overseas visit to Norway in 2018.

The suit worn by Kate was bespoke, made just for her, and not currently sold by Burberry in that colourway.

Mette-Marit wore a shimmering dress by The Vampire's Wife, the Falconetti dress, that Kate also owns in emerald green.
