How do you stretch jeans overnight mine are too tight in thighs leg hole at bottom and waist?

To stretch your jeans overnight, dampen the areas that are too tight using a spray bottle filled with water. Put the jeans on while they're damp and move around to help them stretch to your shape. Alternatively, you can lay the jeans flat and gently pull on the tight areas, then leave them to air dry. Another option is to wear them while sitting in a warm bath, as the heat can help the fabric relax.
