For Louboutin shoes, "nude" doesn't just mean white
"Nude" in cosmetics and fashion has historically been used to refer to the skin color of white (pink?) people. In an effort to be not racist, Christian Louboutin has become the first major luxury label to make shoes in a wide variety of skin tones.
We weren't aware that disguising your high heels to blend in with your feet skin was a thing really, but we're glad to see that it's at least an available option to everybody regardless of their skin color.
