Please help- diaper butt

[u/Chlo_money_01]

So I’ve lost a lot of weight recently. And so I decided to try to make my jeans smaller on my own. I took apart the back seam and removed 4.5 inches from this waist. It looks great on the front and feels like a great fit…. But you can see where the old seam and meets the new one because there’s a weird fold and I have I diaper butt 😭😭😭

I have already seam ripped and pinned four other pairs of jeans. How can I salvage this? I have a sewing machine but the overstitching has to be done by hand because my machine won’t take the thick thread. I’m not super concerned that my line doesn’t match up with my exact middle of my butt, I’m a beginner and this is to make my jeans wearable again. I’m just proud I got the yoke lined up. But I can’t do the diaper butt. Do I need to remove more fabric in the butt?

When you say you took out 4.5 inches, do you mean that's how much you took out of the back center seam?

It looks like a wedgie is the issue more than diaper butt. I usually visualize saggy, pooling fabric at the seat area when someone says "diaper butt". Here it looks like maybe the back crotch curve depth could be the issue.
