For footwear, Sophie wore her Gianvito Rossi Gianvito 85 pumps in nude leather.

The shoes cost a whopping £560 on Net-A-Porter.

Sophie’s outfit draws many comparisons to Princess Diana’s retro polka dot looks from the 1980s.

In 1986, on the royal tour of Japan, Princess Diana wore a Catherine Walker printed peach, silk, polka dot dress.
