Another gown I've taken pictures of recently is this one-piece round gown at the Helen Geier Flynt Textile Gallery in Historic Deerfield, MA., United States. This gown is similar to the gown we will be making in a 1780s Costume Workshop in Canberra, Australia from 1-3 October 2011.

When you look closely at the sides you see that the gown has a drop-front. Without having an opportunity to look closer, I am guessing that it could be worn with ties to the front skirt piece tied at the back or pinned to the corset. The bodice and sleeves are lined with plain linen and the pleated back has a centre back seam.
