I love my new jacket, the fit is amazing and it is very comfortable. The sleeves are the greatest. The slim arm is perfect.
I did have a problem with the collar. It didn't sit right on my neck and I had to redo the entire thing, ripping out the edge stitching and top stitching was pretty hard to do with black on black, thread and fabric. I got it done and altered the collar shape to hug my neck better and redid it.
I used a Lekala pattern for the basic shape and fit but altered every single pattern piece. I first taped all the pieces together then redrew what I wanted changed cut it out and added seam allowances.
I love Lekala patterns because they fit so well and because I can add my own seam allowances. I use various sizes so I don't have to trim seams. I always use 1/4 for collars and neck edge, 1/2 for sleeves and if I have seams for detail they get 1/4 also. I use 1in. for zippers and 1 or 5/8 for body. Makes it easy for me.
