There are two "B" gores at each hip, the busk is 12", there are four 1/2" bones (around the grommets) and I have 20 1/4" bones around the rest. Although I didn't need them for bust support anymore, I still put three bones in each side-bust panel. In only one set of panels did I forget to take the layers apart before sewing the boning tape to the coutil, so most of the bones are not obvious.
The measurements while laying flat are:
Waist to underbust: 5"
I put these on hastily, so the lacing is uneven and the skirt isn't completely square. But then, perhaps I just had it pulled too tight. Also, I KNOW this was cut out precisely on grain (it's rather easy if you happen to draw a line along a twill change, then lay the pattern piece over that, with the grain line right over the drawn line, right?) but the busk twists anyway. I guess that means my body is the problem. Phooey.
