Earlier this week, the Duchess of York made an appearance at both Safety Bay High School and Waikiki Primary School in Australia - and her dress was a major head-turner.
Sarah Ferguson, 65, was seen wearing a black polka dot dress as she read to a group of school children which featured a lovely white collar and pearls for buttons.
The classic polka dot number also featured long sleeves that cinched at the wrist and a floaty knee-length skirt.
