While wraparound sunglasses are not very mainstream, fans of the look can buy similar sunglasses to Anne at Marks and Spencer for just £20. As well as her Adidas pair, the princess has been spotted wearing numerous glasses of the same style over the years.

Anne's international trip will also involve the unveiling of the Cape Town Labour Corps Memorial, which will "commemorate more than 1,700 predominantly Black South Africans who died in World War I between 3 and 14 August 1914 and who have no known gravesite," per Hello! magazine.

Princess Anne was forced to undertake a royal tour of South Africa solo after her husband, Vice Admiral Sir Timothy Laurence, was injured at their home, Gatcombe Park. His injury comes seven months after the Princess Royal was hospitalized with a concussion following her own injury on the estate.
