I ordered these in black due to the 98% cotton &  2% spandex.  I prefer 100% cotton as they do not stretch out like the others, but this is as close as I can find.  The fit is exact, I am 5'6" 129lbs, so size 4.  But, after wearing these just once for a few hours they  stretched out in the back & and waist were/are terribly baggy.  I think it's the spandex.  These actually stretched out more than the blue, that have cotton, poly & spandex.
