Princess Diana, one of the most influential style icons of the 20th century, was known for wearing a lot of classic designer brands, from Jimmy Choo to Christian Dior. But there was one fashion house she avoided after her very public divorce from Prince Charles.According to designer Jayson Brundson, who spoke with Harper’s Bazaar Australia about working with Diana in 1996, Diana couldn’t bring herself to wear Chanel because of the label’s iconic double C logo.
