It's less flashy, for sure, but it seems fitting at the moment. The news can be overwhelming, many of us are worried about loved ones, along with our own health, and the economy is on shaky ground. It seems safer to invest in pieces that are solidly built without a lot of bells and whistles. The details are subtle and utilitarian. And it seems I'm not the only one thinking this way.

A burgeoning brand like Entireworld, which specializes in superior sweats, socks and underwear, has seen an unprecedented surge in sales—662% over last year, at a time when many brands and retailers are struggling. Ralph Lauren introduced the Icons Shop, a collection of enduring styles from the Polo archive that stand the test of time. Todd Snyder now makes a denim shirt cut from hardy cotton by Italy's renowned Albiate mill and finished with substantial melamine buttons. This is an old school shirt that will always feel fresh.

According to David Morris, MR PORTER's buying manager, “customer interests have shifted toward classic and versatile pieces.” He says that basic T-shirts from their house brand, Mr P., have been selling like crazy. “Sneakers, as a category, seem rather obvious during these times, but it's been interesting to see brands like Common Projects and their timeless styles remain as relevant as ever to our customers.”

Morris also says he's noticed a huge appetite for familiar pieces with a throwback quality. “There's been a global desire for soft and easy garments,” he says. “A tailored chino or a great pair of sweatpants go a long way during these nesting times.” Even at a luxury level, this isn't about frivolity. It may be slightly indulgent, but only in the sense that these are pieces worthy of the investment. And it feels good to buy something you know will be sticking with you for a while—and long after we're able to freely go outside with bare faces.
