What do you call this problem when your pants, especially jeans, look like sticking out in the front and look as if there is a pillow on their knee part? (As if it has taken the shape of the knee.)
I don't mean "to be worn out", "to get folded or creased", or "to get faded". Unfortunately, I don't know how else to describe it, I mean exactly the way it is shown in the following picture (by arrow).
For example:
"I don't like it when my jeans ____(at the knees)."

sounds pretty good to me
