My husband has other Levis 501's and these new ones are different in the weight of fabric ( light), fit(tighter in the leg and crotch) and color of stiching(white). Also the rivits and buttons are white instead of metal color.  They also shrank when washed in cold water and line dried.  Are these real Levis 501's or knock off's ?They are made in Mexico, his older ones are made in Colombia and are regular heavy fabric Levi 501 work pants. We are not happy with these pants but have already washed and used them. We would never order them again.
