Justice Ruth Bader Ginsburg was famous for her stylish collars (called jabots) and her commanding dissents. This opera-loving New Yorker always spoke her mind; as a young lawyer, RBG advocated for gender equality and women's rights when few others did. She gained attention for the cases she won when arguing in front of the Supreme Court, before taking her place on the bench in 1993.
