This is a lovely shade of green silk, with a matching net and trimmings. I have had this collection of fabric sense the last miniature show I went to years ago. The gown is an evening dress in the same era as I have been working in, the 1820's. The bottom of the gown was often gathered and puffed like this and trimmed out in different ways to accent the design. It made the bottom of the gown "stand" in a circle around the body, from the stiffness of all the gathered fabric or net etc. So on to the next gown.
