As for the retro items listed, several have also been quietly gathering steam over the previous year. Retro sneakers, for instance, have seen a major resurgence lately. According to research firm NPD Group, sales of classic sneakers are up 27% heading into the holiday, making it the fastest-growing category of athletic footwear. In a press release, Matt Powell, NPD’s sports industry analyst, called it “the most important fashion trend for this holiday season.”

The Adidas Superstar appears to be positioned at the top of the wave, as different audiences have embraced it. Fashion insiders, for instance, have increasingly turned to the “shell toe” as the industry’s favorite sneaker, Adidas’ classic Stan Smith, has become ubiquitous. The shoe has a permanent place in hip-hop sneaker culture after Run-D.M.C’s song, “My Adidas.”

Fashion has also been slowly rediscovering its love of classic Levi’s jeans, which ceded ground over the years to premium denim, and more recently, to the stretchy, workout-inspired comfort of yoga pants. And bomber jackets are everywhere again thanks in large part to some of the biggest names in hip-hop and fashion bringing streetwear back into the spotlight and the runway.

There may be no better illustration of these trends than the ultra-hyped, Paris-based label Vetements. Its reworked Levi’s and oddly proportioned bombers have become a signifier of cool in the fashion world, earning fans like Kanye West. Vetements’ leader, Demna Gvasalia, has recently been appointed as creative director of luxury fashion house Balenciaga.

If Google’s trend analysis is right, maybe Gvasalia’s next design should be an adult onesie.
