Over the shoulder

The last time I bought a backpack was about twenty years ago. Until I saw the Chanel show, I thought that this would pretty much be it. But then Karl sent a couple of great models down the Grand Palais, and the hungry and greedy I surfaced. They come in all shapes and sizes. A lot is possible and allowed. As long as you keep to two important rules. The backpack must never be worn on your belly. Never. And even though it has two straps, it is not allowed to wear the backpack slung over both shoulders. Nonchalant souplesse is the word. Basta.
