I have 2 pair of these jeans. One from China has thick, very elastic material, the other from Pakistan has slightly stretchy, and thinner material.  I love the latter pair.  The first pair shrunk in both length and width and They feel like leggings when I first wear them; they most definitely have more than 1% spandex in them-they stretch like a pair of tights.  The second pair shrunk only slightly and I wear them much more often.  What happened to the quality control? for the amount of money they charge and their cost to produce one would hope that they pay attention to at least the materials they use.  And from all the other reviews sizing seems to be an issue.  Pattern standardization costs cents.  I love my Levis when they fit right but it is getting harder and harder to achieve that goal.
