I saw a beige caviar jumbo in a Chanel store yesterday, and the tears around the stitching show so clearly. Each time a thread goes into the leather, some cracks are inevitable around the stitch, but on the beige it showed up so clearly because the underside of the beige is white/gray, not beige.
I'm not sure if the bag was returned or something but it really put me off. If you are getting a beige, make sure you pay attention to the stitching.
