to this vibrant Philip Somerville red parasisal picture hat with fuchsia pleated brim worn by the late Princess of Wales on March 14, 1989 during a tour of the Persian Gulf. Interesting note- in the first gallery, the hat is shown trimmed with the same brass button as on the coordinating Catherine Walker dress. In the second gallery, it the button is red. I wonder what prompted the change?!
