Idol Red #52
A playful red-orange that channels Kate's rebellious, rocker-cool late-night style (artfully paired with a black latex dress and metallic silver leather jacket). Kate told us that the shade was inspired by the '80s, specifically "Blondie. . . Debbie Harry [and] those gorgeous, glamorous punk girls." She also said she wears it on "those days when I want to try something a bit edgier."
