I was trying one of my vintage jackets and this particular one has bugged me since I got it because this crease from the lapel forms down the chest when I wear it. I can't seem to figure out what is causing this. The shoulders fit fine, they arent too small, overall the jacket fits perfect, except that this crease/wrinkle forms when I put it on. It has high armholes so maybe that's causing it? Any suggestions on what the problem could be appreciated. I drew a picture to illustrate (the 2 circled areas) since i don't have anyone around to shoot a pic.
