In the "Era of the Hoop", not all women wore cage or covered crinolines at all times, for both economic and practical reasons. When doing farm or household chores, evidence suggests that some women opted simply to wear a few layers of petticoats or revert to the pre-crinoline era corded petticoat to support their skirts. For a poorer woman, regular petticoats or a homemade corded petticoat might be the only option within her economic reach. http://home.comcast.net/~lynnegaither/index.html
