A Ladies Guide to Making 18th Century Stays

Over the past few days I have been spending all of my time working on a new pair of 18th century stays to go underneath the Robe a la Francaise.
I used the American Duchess stays pattern as a tentative base, then altered it with the help of extant garments, other historical costumers advice, and a little imagination. Since this project is going to be entirely hand sewn and will take quite a while to complete, I thought that I would make a bit of a step-by-step of how I created them. Please don't take this as a guide to sew your own though, since I'm not focusing on historical accuracy. I just want a mostly accurate shape and a pretty garment at the end of this.

A look at the paper pattern piece of the center front panel

The two back panels of the stays

After drafting the pattern on paper and adjusting it a million times to get a better fit (okay, it wasn't a million, but it sure felt like it), I cut out each section for three layers: two inside layers (where the boning will be sandwiched between) and the top silk layer. I then copied my boning pattern onto the inside layer so that I can follow that with my stitching. The boning pattern took me nearly as long as actually drafting the shape of the stays, just because I wanted to make sure that it was both comfortable and efficient. I also wanted to follow a historical example, since seamstresses through history always knew best. It can be pretty difficult to find clear photos of extant stays, but I used this one from the V&A as inspiration, since it doesn't have a front and back lacing. I cut out my front panel as just one piece, so it won't have the option of front lacing.

After all of the boning channels are drawn onto one of the inside layers, I pad stitched the layers together. Pad stitching is a type of tailors stitch that bastes two layers together (this is how you attach a non-fusible interfacing). I did this quickly and a bit sloppily, since I just need it to make sure that the layers don't slip while I'm stitching the channels. The sections especially needed it because of how slippery the silk is. I then ironed everything before I started any of the real stitching.

The boning channels in one panel entirely sewn up, but with the pad stitching still in. I will be removing that in a while.

Now it is finally time to start on the boning channels! This could be a very tedious process since it is just a running stitch down all of the lines you drew for your boning channels, but I actually really enjoy the process. So far I've watched Crimson Peak, some Ripper Street, and Marie Antoinette while working on my sewing!

Before I sign off, I thought that I would talk through a bit of my thought process behind the decisions I've made so far in the process. To begin with, I am including the top layer while sewing the boning channels because I want to see the stitching from the front. I have seen some more decorative stays where the top layer was sewn separately and then attached after the bones were put in, but I love the texture of the stitches and want to be able to see that once the stays are done. 
Another thing that I would like to mention is my choice of silk that makes up the top layer. I am very aware that it isn't historically accurate (though it does have a vintage flair to it). I decided on this one for a few reasons: one is that I only had a meter of it, so it was the perfect amount for a project like this. Second, I want the final piece to have a bit of a modern Marie Antoinette style, and I thought that this would be a great way to achieve that. Thirdly, I just really like the colour and how it looks!
