His eyes and smile gleam with amusement, his hands held wide as he describes his method of reverse engineering the recipe of design, decoration, patina, ambience and the rest resulting in the atmosphere that gave him such ineffable joy. “When I design clothes, I’m building up those elements, that formula that I believe excited me. I use the formula to design clothes. So then, hopefully, the clothes will be as honest as a national park.”

We’re not now in Yosemite, but about 100 or so miles due south through the Sierra National Forest, at the Sequoia National Park – specifically, on the trail of 100 giants, an asphalt path wending its way through a grove of towering burnt-umber titans, some of them older than any Mesoamerican pyramid, and three times as tall. Everywhere here, the trees, and the white granite walls of nearby promontories, dwarf us. Distance and dimension are flattened so that every landscape, in every direction, looks like the Kodachrome vistas of an old Life magazine – idealised images, often of happy families car-camping through the parks of the West with abundant mid-century optimism. This is a happy place and those are happy associations for Mr Nakamura, whose fascination with garments and textiles was born out of his collecting of vintage denim and workwear from the mid-20th century, and who brims with the kind of Crest-white optimism of the day-trippers in old editions of Holiday magazine. “So,” he says, “when MR PORTER approached me to design a capsule collection inspired by the national parks, it made perfect sense. Because we come here a lot.”
