Finally I have something to show! After MANY MANY drafts (so many it was insane for me to have shown them all) I sized the pattern to fit Josephine
As you can see I focused on the princess seams and didn't bother putting a ruffle on the muslin since that's the easy part (so to speak). This isn't actually closed in the back, but I had it pinned earlier and it definitely fits! I did, however, run into a snag. I hadn't counted on the pattern pieces being so narrow - too narrow to use the wonderful cookie fabric I'd planned on. So I dug through my stash and found a Christmas pattern of little holly leaves and berries on white - so Josephine will have a Christmas dress rather than an everyday one. I'm about halfway done sewing it and Kawaii doesn't begin to describe it!
