Breastival Vestibule is an installation of inflatable architecture exploring the effects of societal norms that live inside each of us, and practices of resistance to presumed limitations. The project specifically examines the practice of toplessness by women within and outside of mainstream society. 1970s feminisms gave birth to an explosion of utopian subcultures and practices. 40 years later, what does our current relationship to these movements have to show about our personal and cultural relationships to body? What does this articulate about sex and gender-based oppression and violence in the 21st Century? Breastival Vestibule attempts to engage with these topics through a collection of responses to questions posed in workshops, interviews, and questionnaires.
