New chanel ballet flats

I bought these before I got pregnant. Never got to wear them and unfortunately due to pregnancy my feet have changed so they don’t fit comfortably. I need to buy a bigger size. They come with the original box and two dust bags. They were only worn once from the house to the car and back. The wrinkles on the back are normal to this kind of leather. I usually wear a size 8 but for me these fit short and wider. Beige Lamb skin and black cap toe with the CC.
