RACHEL'S COMMENTS
Amazing dedication to historical garment research! (http://craftyagatha.blogspot.com/)
I actually used a modern bra cup shape for my pattern shaping. By cutting out the cups and cutting them in half vertically, I was able to then shape the cups to provide full coverage and used those shapes as my pattern.
I have been wanting to try this too, ever since they found that bra in the wall a few years back. More pics? How does it fasten?
It is fastened along both sides with lacing through eyelets. It is completely hand sewn using waxed linen thread. I have a blog craftyagatha.blogspot.com, if you are interested in seeing more pictures.
You have done so much research on this thing! And to get so in depth into how to most authentically recreate this garment is astonishing and wonderful. Vivat!
Thank you for sharing your work with such a wide audience. Who wouldn't feel pretty wearing such a lovely garment? Alicia
The lacy material between the cups is called sprang, a plaiting technique. It provides structure as well as being pretty.
