Nobody in this photo is dressed up. Sweatshirt, jeans, a cardigan, a white shirt, sneakers. It is a weekday walk across cobbles in central Madrid and everyone is wearing what they grabbed. And yet the whole frame looks composed, which is the thing people mean when they say Europeans are effortlessly cool. The effort is real, it just went in months earlier, at the point of buying. Once you own the right things, casual takes about four seconds.
