Frederick native McCardell was a trailblazing fashion designer who made revolutionary designs that helped women live independent lives. From the 1930s through the 1950s, McCardell pioneered ingenious new designs — from separates to ballet flats to leggings—that remain staples of our wardrobes today. Dickinson is currently writing a book about McCardell, who helped invent American fashion and forever changed how we dress.
