Kate Middleton and Prince William arrived in Rawalpindi and the Duchess looked elegant in a stunning turquoise shalwar-kameez by Catherine Walker.
The 37-year-old wore the national dress of Pakistan – a long shift over the top of trousers – as she arrived at Nur Khan air base.
The turquoise, bespoke outfit appeared to be ombre in colour, with a lighter shade transitioning into a deeper hue towards the hem.
Kate teamed the outfit with nude heels and wore her hair down with a pair of dazzling earrings.
Speaking about the outfit, royal correspondent Emily Andrews said: “The Duke & Duchess of Cambridge arrive in Pakistan at Nur Khan air base in Rawalpindi.
“Greeted by the British High Commissioner and a Presidential honour guard.
“Kate’s shalwar kameez by Diana’s fave Catherine Walker [is] a nod to her host country.”
According to Gov.uk, men and women visiting Pakistan should dress modestly at all times, with shoulders and legs covered when in public.
The Duke and Duchess of Cambridge looked happy and relaxed as they arrived for their four-day trip and were each presented with a bouquet of flowers as they walked down the red carpet at the air base.
The couple will visit Islamabad for four days between October 14 and 18 in what will be their first visit to the country.
They are expected to meet political and cultural leaders, see how communities in Pakistan are responding to the impacts of climate change, and deepen their understanding of unrest in the region.
The last royal visit to the country was made by the Prince of Wales and Duchess of Cornwall in 2006.
The royal couple will also be following in the footsteps of the Duke’s mother, Princess Diana, who visited Pakistan three times during her life.
Her visits saw her lay a wreath at Commonwealth war graves, tour Lahore’s iconic Badshahi Mosque, and visit a centre for disabled Afghan refugees.
The visit has already provided a boost to Pakistan’s retail industry. Last week, stock of a pair of £6 earrings by Pakistani designer Zeen sold out minutes after the Duchess was seen wearing them at an event in London.
Yusra Askari, a spokesperson for industry body Fashion Pakistan, said: “The Duchess of Cambridge is a global fashion icon and trend setter.
“(It’s) time for Pakistani designers and the country’s fashion industry to brace for the ‘Kate Effect’.”
