The puffy white monstrosity is done. It took me two days to gather the fabric and only about an hour to actually sew and assemble the thing. It looks sort of wrong in the picture, but the shape should be just right with the support the dress gives. I looked and looked at the portrait for some sort of fastening, like the ties on other partlets. but didn't see one. It didn't seem to have an underarm seam either. That just doesn't work with the pointed look of this particular shape. All I can figure is that it is pinned into place. It sits fine now, but could easily be twisted if it isn't anchored in some way. I might starch the collar just a little to give me more the look that is in the portrait.
