So I went after my partlet with a pair of scissors. And after cutting off a whole bunch, it shockingly fit pretty well?
Compare the new chopped up pattern to the original:
You can see I smoothed out the neck-to-front piece like whoa, and didn’t really leave any curve there. Also made the front-to-back transition hit in a better place, and took out a bunch of that width.
I have enough silk organza, but alas not to cut it as a single piece so there is going to be a seam up the back.
