This is made from a pattern that was given to my Mother by a member of the SCA. We have lovingly referred to it as the "Fishwife's Bodice" for many years. I lengthened the original pattern, though, and was careful about the straps, as they always seem to be a bit wacky.
This is the back of the bodice, which *does* lace at the side-back seams. This is an important feature for adjustability. In this way, if my friend is having a bad-breathing day, she can loosen it up at the sides and not just the front.
While the idea was to make a soft-bodice, I will say that the entire thing is interfaced with duck canvas and boned at the grommets with nylon cable-ties. This makes it impossible for those grommets to bunch and pucker, and it gives the bodice a "solid" look.
The shoulders of the pattern are also grommetted, which is another adjustability feature.
