Coco Chanel was probably SLI.
Her mother died and she was raised in an orphanage where she learnt to sew. She changed the history of fashion forever when motivated for the uncomfortable clothing (corset and huge dresses) of the age, start designing and using her own clothing while being in parties of rich people. She introduced minimalism in clothing for women, trousers for females, jerseys, branded perfume, natural tanned skin, cheap costume jewelry (for those who cannot spend in real gems), black dress (because brilliant colors make her feel ill), and suits for women.
