I love love LOVE these new Chanels! Howevah.. the Dallas boutique doesn't have them in stock and the only size I can find to order is a 40.5. I can wear anything from a 39-40.5 depending on the shoe, but I've never bought a Chanel before. thoughts? If they run like Manolos I will be fine.. if not, I will be heartbroken when they arrive! Help!
