Princess Diana’s complex

What complex did Princess Diana suffer from? She was 5 feet 10 inches tall, which made her very self-conscious, slouched and had a curvature of the spine. In addition, Diana was the same height as Prince Charles, so she had to choose shoes with low heels, and in all official photos of the couple Diana deliberately "made" lower, sat on a chair, or forced to sit down. This exacerbated her complex.
