Kate Middleton and Meghan Markle were not included in a duchess-focused list by Tatler.

The Duchess of Cambridge and Duchess of Sussex are among the most popular and most photographed royals at present. However, according to Carly Read, a journalist for Express, both Middleton and Markle didn’t make it to Tatler’s Duchess Power List.

The list includes Duchess of Richmond (Janet Elizabeth Gordon-Lennox), Duchess of Rutland (Emma Manners) and Duchess of Northumberland (Jane Percy).

It remains unknown how the magazine picked the duchesses who made the cut for their list. But recently, Vogue editor-in-chief Edward Enninful expressed his interest in featuring the Duchess of Sussex on the magazine cover.

According to Enninful, he is very enthusiastic about the younger members of the royal family. When asked to choose who between Middleton and Markle has the better fashion sense, he declined to give an answer but said that the two royals have different fashion choices. He then added that he wanted both to be on the cover of Vogue.

Princess Diana and Middleton have already graced the cover of the magazine. The late Princess of Wales appeared on the front cover four times in 1981, 1991, 1994 and 1997. On the other hand, Middleton graced its cover for its centenary issue in 2016.

The magazine also featured Prince Andrew and Sarah Ferguson’s daughters Princess Eugenie and Princess Beatrice last September. However, unlike Princess Diana and Middleton, the royal princesses were not on the cover.

Although Middleton and Markle didn’t make it to Tatler’s list, they were among the most powerful fashion influencers in 2018. Lyst put the Duchess of Sussex at the third spot next to Kim Kardashian and Kylie Jenner, who ranked second and first, respectively.

According to the magazine, Markle proved her royal style credentials by wearing heritage British brands like Barbour, Hunter and Burberry. She also spiked searches for lesser known brands like Misha Nonoo and Finlay & Co.

On the other hand, Middleton landed the 16th place. The Duchess of Cambridge was ranked fifth in 2017 and was out of the top 10 last year. The magazine praised Middleton for continuing to spark global demands for her looks by using the designs of Erdem, L.K. Bennett, Roland Mouret and Dolce & Gabbana.
