I got my first Chloe in the mail today! It's the black medium silverado doctor. It looks so rock n' roll and very Balenciaga to me (sorry, B-bag lover here :shame!! I'm taking it to work with me tomorrow. By the way, does anyone know what kind of leather this is? Is it regular cow leather? I heard it's untreated leather... And what are the two little leather rings/bands on the 2 shoulder straps use for? Is it to keep the straps together?
