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:

There are other models, which do not cover as much, and instead are meant to be worn over regular pants.
Example snow pants from Google Image Search for "snow pants":
