Princess Diana's royal wedding to King Charles took place on July 29, 1981. Diana's wedding gown was inspired by a supermodel's "fairytale" dress, but body language experts suggested the royal was "shy" at her nuptials. And according to Diana herself, her own mother's behavior was a huge source of contention at the iconic royal wedding.
In the biography Diana: Her True Story—In Her Own Words, Andrew Morton discussed Princess Diana's thoughts on her mother's behavior at the wedding. According to Morton, Diana felt "let down terribly" by her mom, Frances Shand Kydd, at the royal wedding in July 1981, via the Daily Mail.
