Ta-da! A copy of a dress by the great Madeline Vionnet.
The pattern for this dress comes from the Japanese pattern book on Madeline Vionnet, which I reviewed earlier here. The present post is just a brief pattern review-- I made a muslin and it turned out well enough to write about-- but I'll post a full review later, when I make the final dress.
I'm planning to make the final dress out of four-ply silk crepe, which is very expensive. I needed to make a muslin first, but since this design relies to heavily on the drape of the fabric for its final form, I couldn't use regular muslin. So, I dug through my stash and found some drapey fabric I that I didn't like. This brownish stretch silk crepe de chine fit the bill. When I first ordered it, I didn't expect it to be this color, which somehow alternates between awesome and awful. I also didn't expect it to be stretch fabric, which I generally hate working with. The drape and the handling characteristics of stretch silk crepe de chine are very different from the non-stretch variety.
This pattern is very unusual. It consists of three pieces, one which comprises most of the dress and is stitched together in the front, and two gussets inserted into the back bodice, which helps form the casing for the strap. The piece which comprises most of the dress was too large to fit on 45" wide fabric, so I had to cut it from two separate pieces, then sew it together.
The pattern instructions were in Japanese, so I had to go by the pictures, which didn't illustrate all the necessary steps. I'll see if I can write a full set of instructions when I make the final dress.
