Q. Where can I learn more about historic Brethren plain clothing?
The Brethren reference library holds some books on plain clothing. The Reuel B. Pritchett Museum Collection holds some samples of plain clothing: all are available for viewing in Special Collections by appointment.
In addition, you can find plain clothing information and advertisements in some of the periodicals digitized in the Brethren Digital Archives: https://archive.org/details/brethrendigitalarchives
