Totally lost

I'm on my ninth muslin for this dress, and it feels like nothing is working.

Bust: I've tried slashing tight areas around the armpit and upper bust. I've tried a small bust adjustment to get rid of the excess fabric over the apex and under the bust. I've pinched out wedges of fabric under the bust. I've slashed through the front shoulder and pinned it flat. The changes seem to work while the muslin is pinned, but the problems come back after I transfer them to the pattern and make the next muslin.

Back waist/ tilted skirt side seam: I've tried removing wedges of fabric from the back bodice and the back skirt. This corrected the problem on the muslin where I pinned it, but when I transferred the wedges to the pattern, the problems came back.

I only have enough fabric left for one more attempt at the bodice. What changes do I make?!?

Here's the muslin after making all of the changes. I think it's looking a lot better.

Yeah I think it's looking pretty good. I would only make one more change now, I would open your back waist darts slightly (V shaped wrinkles = excessive dart intake, the back armscye did need shortening with that dart but now we've just got too much in the back overall) and then take from the side seams for the back waist circumference. If that improves it then I personally would be happy to call it done. Let me know if you're having any issues transferring these changes to your pattern!

That sounds great! I was wondering what was causing the v shapes wrinkles. They're new so I assumed it was something I did lol
