This trip to Pakistan - and the Khyber Pass - also illustrated a little known but crucial facet of royal tours. Part of Diana's 'job' on this trip was to promote the British-made small plane that flew her to the Pass, demonstrating its capabilities to the Pakistani airline in hopes they would place an order.

This suit became another workhorse for Diana in the early 90's. She wore it to a Buckingham Palace garden party in the summer of 1991, and with the addition of a green straw hat, the outfit became useful to visits to countries where green was a national color - she wore it on the Wales' tour of India in February of 1992 (lower left) where she and Charles placed a wreath at the memorial to Mahatma Ghandi, and In June on a day visit to Belfast, and despite the fact that security demanded only a few hours notice to the people of Belfast, she garnered the largest crowd at that time ever to greet a royal visitor.
