Method number 1
The easiest way to smooth out a rumpled leather jacket is to grab it, hang it on a standard hanger, and let it hang. This method is suitable if the leather from which your leather jacket was sewn is thin enough, and also if your leather jacket has not been hung on a hanger before.
Method number 2
If the first method did not work for you, then take your leather jacket along with the hanger and transfer it to the bathroom. Then open the hot shower and close the bathroom door. This will steam the jacket a little, which will help it straighten out more quickly. Just be sure to make sure that no water gets on your jacket. It will only get worse.
Method number 3
If you have a handheld steamer, you can use it to locally steam the most dented areas of your leather jacket. Keep the steam generator at a distance of 10 centimeters from the leather jacket to avoid the accumulation of condensation on the skin surface. This is the same water that can ruin the look of your leather jacket. You can also use an iron with a steam generator.
Method number 4
The fourth way is to iron your leather jacket. Move the position of the iron thermostat by one, so that the iron is not too hot. You can stroke the skin directly, but I do not recommend doing this. It is better to first try to iron it through wrapping paper, you know, parcels are wrapped in such paper, or through fabric. Do not turn on the steam generator.
Method number 5
The fifth method is as simple as the first. Just take your jacket to a dedicated leather dry cleaner. There you will not only pet it, but also clean it before the new season of cold weather.
