Sarah Seven Palmer Fashionable unclassified dresses

This is a Sarah Seven Palmer dress (part of the Sarah Seven Romantics collection) worn once for my wedding. The label size is 8, but it fits more like a 4 or a 6. The dress was dry cleaned (receipt can be provided) and has no imperfections.  It has a lace bustier/ sweetheart top and crepe/silk bottom with a beautiful lace back and train (with bustle).
