Why do Jeans Shrink and Stretch
Jeans change their shape over time because they are made of cotton. Cotton fibers are woven together like a basket to create the material in your pants.
Normally, 100% cotton material feels stiff. However, things like water and heat affect the strength and size of cotton fibers. When the strength and size of the cotton fibers change, the shape of the cotton can change. That lets you stretch or shrink it.
Cotton shrinks when it gets hot and dry. The heat makes the cotton fibers less strong. When the fibers become weaker, they get smaller and can clump close together. Once the pants cool down to room temperature, the fibers don’t go back to where they were before. Instead, they keep their new, shrunken shape.
On the other hand, cotton can stretch when it gets wet. The cotton absorbs the water and expands. The expanded cotton fibers are stronger than they were before they got wet. What’s more, the wet cotton is strong enough to not break and flexible enough to mold into a new shape.
The catch is that the cotton won’t expand on it’s own. You have to stretch it yourself.

Jeans made with polyester are great if you wash your pants with hot water or dry on high heat.
