Princess Diana left an indelible mark on the world during her life. She touched millions through her humanitarian efforts, and completely rocked the world with how she upended the royal family and ushered in a new era. But her iconic style has always been a part of her legacy.

Through the ‘80s and ‘90s, Princess Diana set trends and put her own contemporary spin on classic cuts and silhouettes. As she matured in her role and became a mother, her style also went through a transformation. But through it all, her looks were consistently classic and elegant.
