The back of the dress is very voluminous partly because fashion, and partly because it's designed to be super adjustable in size.
The skirt and sleeve hems are turned over and whip stitched to the lining, but the neck edge is finished with a self-fabric band. I just used straight grain and eased it around the curves - mostly because it was easier than finding bias on my fabric scraps, but I am also given to understand that bias cut finishing strips were uncommon until the late 1800s because, being cut on such an angle, they can be really wasteful of fabric.
Oh yes, and did I mention, the whole thing was sewn by hand? Because that's a thing. The dress is intended to be able to serve as a teaching tool, so it needed to be done "the old fashioned way", and I think I may have gone a tad overboard on the teensiness of my stitches. The structural stitching is all tiny and even; I'm quite proud of it! In non-visible places I also left the gold basting stitches in (from marrying the fashion fabric and the lining), so that can also demonstrate sewing techniques.
After Christmas I may go back and put a row of roleaux trim around the hem, and maybe futz with the sleeves. I also need to write up an informational booklet to include all the historical information.
gosh it just turned out so pretty!! i just really love it.
