Sashes were worn for rallies, parades, and street speaking. The colors and the small button identify the wearer as a member of the Women's Political Union. The WPU (formerly the Equality League of Self-Supporting Women) was formed by Harriot Stanton Blatch, daughter of Elizabeth Cady Stanton, to bring working class women into the suffrage movement. The WPU was responsible for holding the first large suffrage march in the United States (in New York in 1910).
“Votes for Women” was one of the most popular and recognizable slogans used by members of the woman’s suffrage movement.
