French fashion designer agnès b. has announced the launch of the mémoire, The Snap Cardigan, written by award-winning French journalist Sophie Fontane to celebrate 40 years of the snap cardigan, which has become the emblematic piece of the agnès b. fashion house. Since its creation, the snap cardigan has never stopped evolving—long and short, in cotton fleece or in leather, as a long dress, with a high collar or a simple round neckline, in a wide range of colors, polka dots, or stripes.

The Snap Cardigan will be available from September from assouline.com, for £18.
