Vintage Chanel Classic Double Flap in Black Caviar The universal wearability and simplicity of the Chanel Classic Double Flap solidifies this handbag as an iconic statement piece. In addition, the Classic Flap comes with an endless range of options, including quilting (the iconic classic), black leather and gold hardware. While the Chanel Classic Flap comes in two main variations – single and double – the double flap version has an extra interior flap. This interior flap separates the interior of the handbag from the main exterior flap.
