Example Of My Current Project: A Hopeful Outcome

This is what I'm attempting for my Robe a l'Anglaise, for both the gown and stomacher style. I'm either going for a Super late 1770s or early 1780s, such as these examples show.

And I love this gown in the below portrait. Again with the similar front but with the pinked & scalloped collar.

I have two colors of silk taffeta in my stash that may be going into something similar to this.

One is a sea-foam color, the other a rich gold.
