But none of these things is actually old. They all rely on new technologies; something of the essence survives, recast for a more demanding market. My shirt echoes the style of old-fashioned workwear but it is suspiciously soft. The sunglasses were produced by a company that has made eyewear in New York since the 1870s but mine are made with super-light acetate, not glass. They are authentic but not entirely authentic. And that’s a good thing. We like to indulge nostalgia in improved comfort.
