Ever wonder why all jeans don't shrink and stretch the same? It's all because of sanforization. Essentially, fabric is put into a machine that moistens, stretches, and shrinks it all before it's cut into clothing, meaning that it won't shrink again (or much) after subsequent washes. The result? Clothes that will fit you forever, provided you don't get fat.
