Why did Princess Diana stop using Chanel?

Princess Diana stopped wearing Chanel products prominently because the brand's iconic double C logo reminded her of Charles and Camilla. The intertwined Cs were a painful reminder of her then-husband Prince Charles and his affair with Camilla Parker Bowles. This association became particularly poignant after Diana's separation and subsequent divorce from Charles, leading her to avoid wearing Chanel items that featured the logo. However, she did continue to wear Chanel pieces that did not display the logo openly.
