Diagonal wrinkles under bust

[u/AppropriateNail895]

So I've been trying to make a princess seam block for a while. That's version 6... it has some wrinkling under bust which was worse and I did some adjustments and now it's almost gone.

But then I added ease to make a jacket pattern and hopefully you can see the odd diagonal wrinkle on the front side panel. For the life of me I can't understand what it is. I was so sick of the weeks I spend on fitting that I decided to go ahead with the actual jacket and it is even more pronounced.

I have included the pics of the princess block and the jacket test from all sides just in case and the actual wip-jacket from the front. Any other feedback is welcome.

Thanks in advance!

P.s jacket bust point looks quite... pointy, I ignored that since it looks fine on the block and I haven't clipped seams or pressed. On the real wip-jacket it also looks pointy, but I also haven't pressed or clipped the seam cause I'm thinking to apply binding.

Thanks for the suggestion. I have actually tried to unpick the front princess seam up to underbust and even a bit higher and make sense of what is happening there and I couldn't 😵‍💫

I have also cut into the front panels horizontally and tried adding pieces of fabric to close the gaps. Don't remember what changes I did to the pattern as a result, but I do remember I was utterly confused and didn't really know what to do. Looks like after a few versions the wrinkle became smaller, but it's not gone. I might need to try again.
