Kate Middleton donned a number of Pakistani designers during her visit to Pakistan last month.

On the Royal Tour, she wore outfits by Maheen Khan, Bonanza, Ideas Pret and a monochrome number by Elan, for which she's thanked the designer behind the label, Khadijah Shah.

The Duchess sent Shah a note that read: “Thank you so much for all of your help ahead of my tour to Pakistan. I am so grateful to you and your team for the wonderful selection you made for me to chose from — although having so many beautiful things did make the decision making a little more difficult! I loved the outfit I wore, so thank you for all your time and effort."

While the message was typed out (on custom stationary from Kensington Palace), Middleton did write 'Dear Khadija' herself and also signed her full name at the end.

Shah shared the letter on her Twitter account.

"I was delighted to have even been considered, this is just humbling to a whole different level," wrote Shah, adding, "However what’s most commendable is the consideration, grace and thoughtfulness of HRH the Duchess Catherine, it is no wonder that she is so respected and beloved."
