Do not know what should I make of it

Cut and fit of the trousers are indeed fine, but unsettled me is the single seam on the inside leg, there are all of Levi's jeans, which I previously bought double seams - for me is close to the suspicion that it was not an original Levis ,
Edit 02:10:13 - have bought in P & C also a Levis and realized that even this has on the inside of the leg just a single seam, apparently there was a change in Levis in the production - nevertheless, the fabric of the Amazon acquired Jeans feels distinctly coarser and stiffer than in the comparison of P & C. Jeans I The rating increased from 1 to 3 stars, because my doubt that it is an imitation pants has been ruled out. When I compare the price, 89 P & C and 56 at Amazon me 3 stars seem ok, only the fabric feels in the P & C-Levis on a fine, but may also be due to the execution, because the Amazon-Jean is significantly darker.
