I have recently bought a large mid-brown Edith (the one you can have on the shoulder). The seller guaranteed the authenticity, but when I compare with other Ediths in the same size (have found only two others), it seems that all three of them have some differences in the stitching. Eg., on mine, the stitching on the both sides (from the bottom and up to the zipper) doesen't stop by the horizontal bold white stith, but has one extra on top. At another one, also guaranteed authentic, the stitching on the zipper puller is made with small stitches instead of large (mine has large). All this differences makes me a bit confucious, is this usual on the Edith bags? Thank you very much in advance!
