Denim jeans are one of the most-owned items by both men and women in the United States, so it makes sense to take care of them properly so they look good for longer. First, always wash jeans in cold water and turn them inside out. This will help retain their shape and won't hurt the finish of the jeans. Skip the dryer and let them dry out on a clothesline. You can even just drape them over a hanger and hang it on a door if a clothing line is not an option. Finally, when it's time to get new jeans, donate your old ones. The most re-sold item at Goodwill is jeans, so it will gladly take them from you to raise money for its charitable works.
