Well thatīs the cause I asked what kind of jacket is wanted.
The short one seems to be meant as a blouson? A blouson will not have front darts, the width would be eased in a (knitted) band. thatīs why these kind of jackets are a bit looser at the front of scye.
When youīr after a tight classical denim jacket, there would be plenty of vertical seams to incorporate all the necessary darts for a skin tight fit.
Now you have added a lounge coat chest dart to a basically shirt pattern. This will not work because in a lounge coat pattern the angles between armhole, shoulder center front, side seam are totally different compared to a shirt. The dart alone doesnīt create length.
I would like you to unpin the front darts and shift the fronts upwards at the side seams for about 2cm. We can look then wich step to take next.
