Okay, here's what happened:
1. I was not successful upsizing the pattern to fit my waist measurements due to the odd gathering of the "wrap around" front panel.
2. Although I was willing to change the design and make it work, I still struggled with getting it to lay right. It worked fine for the mock-up (see?! I was trying to do it right!). I thought maybe it was because I added the flatline pieces so I unstitched it all, removed the flatline and started over.
3. Although removing the flatline pieces did actually get it to lay like I wanted it to, the result of this was that the side seams no longer had the strength of the cotton lining to keep it together so it started to shred apart. Not just pull apart, SHRED apart. (This is a chance you take when you buy second-hand stuff and upcycle it. Curtain fabric is not always woven to withstand vertical seam stress.) There wasn't enough fabric left over to cut new bodice pieces.
4. Sighed. Rolled my eyes up to the Seamstress Goddess. She denied a miracle. Tossed it all in the trash. I did, however, save the sleeve pieces because I might be able to use them for ... I have no idea.
So guess what?! I'm making a whole new outfit from scratch! (So much for that whole not stressing myself out thing.) The blue fabric is left over from Loraina. The lace fabric is actually a modern top I bought several years ago from Maurices. It's a bit too tight now so let's see what I can do with it....! ;-)
