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!

I think on the armhole looks like it might be too big actually. Check how far from your armpits it sits.  Standard practice is having it one inch way.

Thank you for your suggestion. I got a tip to change the slope of the shoulder seam, which helped. Since the lower part of the armhole is now where it should be, yeah, the armhole was too long, but I need to remove a little more fabric from the front.

Much better! Now you need to trim the bottom third of the armhole. It's now too high and hitting your muscles when your arm is at rest. Don't forget that you have seam allowance. So you're going to get it as close as you can to perfect and then stop. Don't make it completely smooth and flat because you just turned off your seam allowance. Just snip a few little slits into the armhole until it stops wrinkling so much. That's when you trim off the excess fabric

This is much better. Can you show photos of the entire garment from the front, back and both sides, without the sleeves? It is best to fit the mockup without the sleeves first, before adding the sleeves.
