NEW CHANEL? Black Quilted Leather Bow Ballet Flats

NEW CHANEL? Black Quilted Leather Bow Ballet Flats in size 42  I got these as a gift and have no idea if they’re authentic or not. I am typically a size 10, and these run very small. I only tried them on and never wore them. They are in perfect, new condition. I think a size 42 is actually an 11, but again, I’m a 10 and they don’t fit me. They’d be best for a 9/9.5 if I had to guess so I’m tagging them that size. They’re slightly short in length for my size 10 foot. I have no box or specific tags. You will just be getting the shoes, unworn.   Elegant Chanel? ballet flats with quilted leather upper. Signature interlocking CC stitched on the toe. Neat bow detail at the vamp. Slip-on style with smooth leather lining.
