When you think about it, the cardigan is a sewn blazer redesigned and transformed in a knitted version. And this is exactly what ça va de soi does best: reinterprets a classic, makes it less rigid, more flexible and softer. With or without a collard, short, or long sleeves, zipped, belted, buttoned, longer or shorter, black, ivory or azure-blue, the cardigan is a must- in all its forms.
