I would say it is a fake.. a tell tale sign of this is the stitching on the quilted portion of the bag. The leather appears almost bubbly, and authentic chanel bags have a flatter effect. The stitch count is higher, so the leather lays flatter and does not have a shiny appearence. It is soft, buttery, and matte like.
My opinion! If I were you I would wait for another reply just to be sure.
