Sisters of Perpetual Indulgence

The Sisters of Perpetual Indulgence (SPI), also called Order of Perpetual Indulgence (OPI), is a charitable, protest, and street performance movement that uses drag and religious imagery to satirize issues of sex, gender, and morality and fundraise for charity. In 1979, a small group of gay men in San Francisco began wearing the attire of Catholic nuns in visible situations using camp to promote various social and political causes in the Castro District.
