Hello, I'm hoping for some guidance in authenticating this cashmere sweater I purchased. The stitching is straight, tight, and even, and there is no "fuzzing" or other textural blemishes. It's a nice weight, very soft. The tag is attached at the top two corners with yard/thread that blends into the sweater. Only one pocket has a logo button, which is attached with the same yard/thread. I was pretty optimistic but having some doubts now, as I read that Chanel tags are completely stitched down, so you cannot put your finger under it (I can - see photo) and that the logos are not attached by stitching (but this is a button, so...) Thanks in advance for any and all opinions!
