Overwashing makes this worse. Jeans actually don’t need to be washed nearly as often as most people think, and frequent washing accelerates fiber breakdown.

Even without high heat, the washing machine itself can cause distortion.
Jeans aren’t gently soaking—they’re being tossed, twisted, and pulled in every direction. When the fabric is wet, it’s heavier and more vulnerable to stretching.
Overloading the washer makes this worse. Clothes tangle together, and certain areas of the jeans get pulled more than others.
Stretch denim is especially sensitive. As it dries, some sections remain under tension while others relax, creating those familiar wavy ripples and puckers.
3. Uneven Drying Locks the Ripples In
Dryers add another layer of trouble. Tumbling causes denim to dry unevenly, and heat “sets” the warped fibers in place.
Once the jeans cool, those ripples aren’t just wrinkles they’re structural changes in the fabric.
That’s why ironing often doesn’t fully fix the problem.
