The royal couple, during a five-day visit, also visited a school and a national park in Islamabad where they interacted with children and admired their artwork. The trip, focused on climate change and education access, is said to be the most challenging one the couple has taken on due to security concerns. The Duke and Duchess of Cambridge also met with Khan at his official residence, with the visit drawing parallels to Princess Diana's visits to Pakistan in the 1990s where she helped raise funds for a cancer hospital. William and Kate also engaged in discussions about education with students at Islamabad Model College for Girls. As they departed, a group of girls sang a Pakistani national song, while the couple said goodbye to preschoolers who were lined up to bid farewell. They then visited the Margallah Hills National Park in Islamabad, which is facing threats from poaching, wildfires, invasive species, and littering. Kate wore a periwinkle blue silk shalwar kameez, the traditional Pakistani outfit consisting of a loose tunic over trousers, for the morning events. Many people on social media and in the fashion industry had been anticipating her wearing this outfit, which Princess Diana had worn during her visits. Designer Maheen Khan expressed her honor on Twitter for being asked to create the outfit for the Duchess. Kate's fashion choices, such as a bright green tunic over white pants to meet with the Prime Minister, seemed to reflect the colors and outfits worn by Diana. Foreign policy experts and officials have stated that the visit, the first by a member of the British royal family in over ten years and arranged by the British foreign office, was seen as a strategy to enhance soft power and advance diplomatic goals for both countries. This comes at a time when Britain is trying to strengthen its international ties as it prepares to leave the European Union, and Pakistan is working to improve its global reputation to attract more tourism and investment.
