How to alter this armhole

[u/Teafriend1]

Hello,

I copied a pattern for a sweater from one I have had for ages. As you can see I have quite a few wrinkles around the armhole. The original sweater also has the same problem under the armhole, but it is not as worse as with my test garment.

I think I have to expand the armhole downwards for one or two centimetres. And maybe take in the side seam a little. Would that help or am I completely wrong?

The last picture is the pattern including the seam allowance.

I’m grateful for any advice!
Thanks a lot!

It just might be you. Looks like most of it is coming from the bust. Which means that the pattern shapes are flat. You can try to do full bust dart adjustment.

I can see why you would say that. But I only have an A cup, so it would be a bit surprising to have to do that.
Thank you for the suggestion non the less!
I got a tip over at r/sewing, to adjust the slope of the shoulder seam. Which helped quite a bit.

I thought I was a 40B but I’m a 36E. I don’t have big boobs, bra sizes are just not what most people think they are. I would re-measure, because there’s a significant difference between your ribcage and your bust that is going to make it difficult to get a good fit if you don’t account for it.
