A black velvet was a popular fabric for this robe over a kirtle. It's a less formal look, and was often worn during pregnancy and nursing. They were often richly embroidered, but since I don't embroider, I used lace.
All hand sewn, I made the piping, and also embroidered and beaded by hand too. It took 80 hours to sew it, and right now it's in my workroom in pieces, being revamped.
