The Chanel Classic Flap is widely regarded as an eternal classic in the fashion world, originally designed by the brand's founder Coco Chanel and reintroduced by Karl Lagerfeld in 1983. It has profoundly influenced handbag design trends globally. One of the signature design elements is its quilted pattern. This quilting not only enhances the bag's look but also strengthens its structure. Another iconic feature is the double-C turnlock, which was added by Karl Lagerfeld during the reissue of the design.
