Nobody shops for shirtwaists anymore. Even those who favor women’s tailored blouses are unlikely to know their traditional name. The word shirtwaist still recalls the worst factory fire in the history of New York City, on March 11, 1911, at the Triangle Waist Factory, also known as the Triangle Shirtwaist Factory. That day, at least 146 workers died, most of them immigrant Jewish women, many jumping through the blazing windows to their deaths. The building, at the corner of Washington and Greene Streets in Greenwich Village, still stands.
