In order to help you out I need a little more info. What’s the jacket made of? Fiber content, blend ratio? How did you wash it? Usually items purchased off the rack have a stabilizing agent on them. Their first wash will remove this. In cottons and cotton blends you can use starch when ironing to bring back the stiffness in the clothing that it had when purchased. Just be frugal with it. It tends to do a lot with very little. Hope that helps.
