I ordered 2 pairs: The blue ones were made in Egypt of 82% cotton, 17% polyester and 1% spandex.  The black ones were made in Mexico of 98% cotton and 2% elastane.  The blue ones are thinner but fit better.  The black ones are thicker but the legs are much tighter than on the blue ones OF THE SAME SIZE.  I read that jeans are cut from 10 layers of cloth at the same time, so the top layer fits the cutter but the bottom layer may shift and not be the exact same cut.  When clothes were made in the USA they always fit the same way.  Now that they are made all over the world the fit is off.  I have bought 3 of the exact same size and style and color Lee jeans in the past and all 3 fit differently and were made in different countries.  So order many and return the ones that don't fit.
