The I and the You: Clothing/Body/Clothing, Lygia Clark 1967
A proposal made for a couple in which both the man and woman wear a plastic boiler suit. Each boiler suit contains within it a lining made up of different materials (plastic bag with water, vegetable spume, rubber etc.). Which gives the man a feminine sensation and a masculine sensation for a woman. A hood, made of the same plastic, blindfolds the eyes of the participants, and a rubber tube, like an umbilical cord, connects the two boiler suits. When they touch each other, the participants discover small openings in their boiler suits (six zips), which give access to the inner lining, translating them into the sensations felt by their partner. In this manner, the man finds himself in the woman, and she discovers herself in his body.
(in reflecting on this statement, I feel like same-sex participants could yield interesting results as well, along with pertaining who would wear the “man” suit and who would wear the “woman” etc.)
