1971 Thea Porter Brocaded Cotton Gauze & Lace Flounce DressThe label on this Thea Porter dress narrows down the dating process for us as it was only produced between October 1971 March 1972. To verify the exact date, I asked Laura McLaws Helms, the author of the book "Thea Porter, Bohemian Chic" and she verified for me that it was indeed from the 1971 collection. It is a beautiful example of Thea's work with a black cotton gauze brocade?? that has red and black diamond medallions scattered over its surface.
