Alternatively, if you want to shrink up your jeans, wash them. It’ll be easier to shrink them up a bit if you do it more quickly after buying them.
If your jeans become soiled, just try brushing them off with a slightly damp washcloth before you wash them. Let them dry thoroughly and reevaluate. If your jeans develop an odor, try wrapping them up in a plastic bag and putting them in the freezer. This is done sometimes to help deodorize jeans. [1] X Research source
You don’t necessarily need to use the washing machine, either. If you just want to freshen them up, get your jeans wet in the tub, ring them out, and hang them up to try. Wash jeans inside out to protect the outside from getting too dinged up in the washing machine. This helps to protect the fibers and the look of the denim. [3] X Research source
Your jeans will eventually fade after a while. The first time you wash your jeans they can shrink up to 2–3 centimeter (0. 79–1. 2 in). in length or width. If you’re worried about them shrinking too much you can buy pre-shrunk jeans. Most jeans are pre-shrunk, but some aren’t.
