Mark Stewart, a veteran royal photographer, has also mentioned the similarity between the two.
'Meghan has the confidence in front of the camera that Diana had, and that same love of fashion and top-end designers, he told the magazine.
'Diana loved Versace; Meghan loves Givenchy. Their style is quite similar: classic, elegant, and with lots of block colours.'
The comparison comes after Markle was snapped wearing Diana’s aquamarine ring - which she also wore at her wedding reception - at an evening reception in Tonga on Thursday.
