From leather sneakers modelled after basketball hightops to tailored track pants, sports have long provided creative inspiration for fashion brands. This season, designers have set their sights a little higher – literally – by taking their cue from alpine sports. At Z Zegna, creative director Alessandro Sartori ushered in “a new era of performance-backed tailoring” with styles inspired by ’70s-style skiwear. And then there’s the collaboration between innovative Japanese label Sacai and American outdoor-gear specialist The North Face, which sees the latter’s weatherproof jackets updated for the runway (and real life) with fresh forms – such as the bomber jacket – and new colourways. It’s time to chill.
