The invention of the sanforization process in the 1920s reduced the shrinkage of denim fabric down to 1 percent. However, shrinking a pair of jeans enables the wearer to mold the jeans to fit his or her body in a more comfortable way. This is why some jeans are unsanforized, or raw, to cater to those who prefer shrink them to their desired fit.
Make sure to choose the right size of jeans adding a size or two to the waist and inseam to compensate for the shrinkage.
Fill a tub with just enough water to soak the pair of jeans. Turn the pair of jeans inside out and lay them down on the hot water. Make sure that they are soaked all the way through. Let them sit in the hot water for about an hour.
After an hour, hang the pair of jeans on a clothes hanger and allow the water to drip off from it.
Lay the pair of jeans between two dry towels on the floor and press on the towels to soak up more of the moisture. Wear the damp jeans and by the time they are dry, they should be shrunk to fit accordingly.
