Anna Wintour, Tina Brown detail lunch with Princess Diana, weeks before her death

The famed editor-in-chief of Vogue, Anna WIntour, paid tribute to Princess Diana, recalling a time she and fellow media titan Tina Brown met Diana in 1997, just six weeks before Diana's death.

Speaking to Brown at the Women in the World Summit in New York City on Friday, Wintour recounted how she came away from the meeting, which happened at the Four Seasons in New York, with a greater understanding of the pressures of Diana's public life.

"She looked incredible, first of all. That was the most important thing, and she looked fantastic," Wintour said of the green Chanel suit Diana wore to the lunch date, per Entertainment Tonight and E! News. "I heard that she spent a lot of time deciding what to wear to that particular lunch."

"I think that the part of her popularity was that Princess Diana really was so good with the media and was so in tune with them and welcomed them rather than standing back," Wintour added. "In a way, she was certainly the first person in the royal family to understand the benefits of that."

Brown said that she remembered Diana being "terribly lonely," and was struck by "how lovingly she spoke about her boys," Prince William and Prince Harry, who were teenagers at the time.

Elsewhere in their chat, Wintour praised Duchess Meghan, Prince Harry's wife, for "bringing modernity to the royal family."

"I think the image that I have in my mind that I think so many people all over the world have in their mind of the Duchess of Sussex walking down the aisle by herself," she said. "That, to me, was representative of a modern woman... And then looking at her extraordinarily beautiful and proud mother in the pew, to me, that symbolized, 'Goodness, this is going to be a different day for the British royal family.' "
