PM Collection by 925 black velvet rhinestone heels

NWOT, never worn black velvet 2" heels with rhinestones. Size 11M. Missing one rhinestone at the base of the right inside the - see photos for detail. These are so pretty! And in perfect condition, aside from that missing rhinestone. No scuffs or marks anywhere. My mom wears an 11N and does nearly all of her shopping online. She was absolutely in love with these, but said they fit more like a 10 1/2 than an 11. But she was beyond the return window. If they were my size, I'd keep them!
