In leather goods, all possible shapes have more or less been explored, from the simplest, shopping bag or satchel, to the most unusual, like a heart or a book. Halfway between the classic bag and the sassy bag, there is a category that is both wise and offbeat, inspired by the world of luggage. Rigid like boxes and equipped with a handbag handle, these small hybrid bags borrow the lines of a vanity or a case. Inside, a limited daily necessities are invited instead of toiletries or family jewels. For the spring-summer season, luxury houses deliver their version of this neo-vanity. At Lanvin, a rectangle of leather is overhung by a handle in the shape of a cat, at Celine, the cult bag, 16, is available in a mini version, at Carven, the bag becomes a box, rigid and geometric, and, at Chanel, the model is literally inspired by a vanity.
