I ordered these a size larger than my usual size in this style of jeans because I specifically wanted a looser fit.  I already owned two pairs of these, so I didn't read the reviews beforehand.  Well, imagine my surprise when they arrive and fit exactly the same way as my smaller sized jeans!  Even though they were a larger size, they just didn't feel as comfortable as my other pairs.  So, I checked the tag to see what was different and saw that the fabrication is different- 84% cotton, 14% polyester and 2% spandex.
