W.I.P.: 1780s stays and petticoat for polonaise progress

So, I'm happy to tell I actually kept my promise I made in the last post and started sewing the petticoat for my robe à la polonaise. At the moment I've got only half of the trimming on the hem left to do. I got the idea for the pinking of edges from Janet Arnold's Patterns of Fashion I. I guess most of you are familiar with the book and recognize the petticoat I'm talking about. I don't have a real 18th century pinking tool since it's not available anywhere on the web at the moment (Do correct me if I'm wrong.) so I used my pinking shears to imitate the triangular pinking style. It's quite time-consuming and doesn't have the exact same shape of the original 18th century pinking but I'm happy with the result anyway. 

I decided on a pleated trimming style that matches with the trimming on the gown itself.

I found this lovely drawing of a woman sewing with a similar pleated petticoat trimming style.

Also, I mentioned I was making patterns for 1780s stays in a post last September (Was it that long ago, really?!)  and I found the cut pieces last weekend when I was going through my fabric boxes and thought I should make them although I had decided on another pattern. I'm probably going to sell them once they're finished so I 'm not going to make any changes to them according to my size. I do this just purely for fun and to test out the pattern I had picked.
