Princess Diana and Prince Charles’ wedding was lauded to be the “wedding of the century,” particularly due to it being the heir apparent’s wedding ceremony. Preparations were definitely extravagant, and the celebration was meticulously prepared, having about 2,000 guests expected to arrive.

Although the ceremony appeared to be a joyous fairytale with the wedded couple ear to ear in smiles, it would later be revealed as a heavily troubled ceremony underneath the facade. Sources close to the couple have spoken out, showing that both individuals had some trepidation about the wedding.

Charles was actually pressured to wed Diana as his father Prince Philip had famously told him to “marry her or release her.” Undoubtedly, Charles chose to marry her. However, he would later say how he wanted to get out of the wedding.

“I desperately wanted to get out of the wedding in 1981, when during the engagement I discovered just how awful the prospects were having had no chance whatsoever to get to know Diana beforehand,” Charles told biographer Robert Jobson.

Diana’s former employer, Mary Robertson, who was invited by Diana to the wedding, retold of her experience and how she realized that Diana was not as happy as it seemed. It surprised her that out of the 2,000 guests invited, Diana was only allowed to invite 100, showing quite a bit of disparity as to how Diana was treated. She described how vibrant and buzzing with happiness the event was, except to her and the people who actually knew what Diana felt.

“She looked so tense and nervous, she must have had this bracelet incident in her mind,” said Robertson, referring to the bracelet that Charles gave Camilla Parker-Bowles, which Diana previously learned about. “She wasn’t looking her best. We were close enough that you could see even through the veil, she did not look happy.”

Apart from the turmoil behind her eyes, Diana was reported to look too thin and unhealthy. It would later be revealed that Diana had developed an eating disorder due to the stress, reportedly losing 5 inches on her waist in a span of 4 months.

In an audio recording for the documentary “Diana: In Her Own Words,” the Princess of Wales can be heard telling her sisters about backing out of the wedding. Diana was also said to have been heard calling her wedding day the “worst day of [her] life.”
