Get your hat dirty. You can step on your hat, leave it laying on the ground, and wear it in the sun. All of these things are great ways to speed up the wear and tear on your hat.
There is a possibility that soaking your hat in hot water can cause its color to slightly fade. This will help your hat to look more worn. If you don’t want the color to fade, soak your hat in cold water instead. If you soak your hat in cold water, soak it for 2-3 hours.
Be sure to take off your hat at some point during the shower to wash your hair, then put the hat back on for the remainder of your shower.
If you have a wool or cotton cap, you can shrink it in the dryer to fit your head. You’ll need to get a hat that is slightly too big or you, and then put in in the dryer to shrink it after washing it. If the hat shrinks too much, wash it again, and let it air dry on your head to stretch it out to the perfect size.
You can also use a baseball instead of a can or glass. This will be a bit harder to hold in place with a rubber band, but is doable and will get you similar results.
