I am finding 17th c bodies to be deceptively simple in construction. The pattern on Drea Leed's Online Corset generator is a single piece...how cool is that? The original ones were made of 3 pieces tho, each made separate and then whip stitched together to assemble. This was so that if a person's weight or proportion changed, they could simply unpick the sides, and add a different back piece, as alot of them were front closing. This front closing type leaves NO ROOM for adjustment, they must fit perfectly, and come tightly together in the front, with no space. I wonder if they laced them over a busk???? hmmmmmm.....that is an interesting thought isn't it?? In any case, Marguarite is a dollye, and hers need not be 100% accurate, which, on her smaller scale, is why I am not cutting this pattern into three pieces, I am leaving it one. Another interesting thing about 17th c corsets you all may not know, or realize, is that they are meant to give a rigid FRONT to the body, and so they are normally only boned in the front. They are supposed to be extremely comfortable to wear, if they are not, then you are not wearing the bodies correctly. They do not 'suck in' anything, no matter how tight you lace them, the small waste you see in paintings and the like, is merely an illusion created by the long extended front point.
I cut each of my 3 fabrics with no seam allowance, as they will be bound around all edges. If you are going to make one along with me, cut your pieces out on the straight of grain!
