This past June in Paris I was sitting in the lobby bar of the InterContinental hotel, catching up with a prominent boutique owner after the Haider Ackermann menswear show. She was in dour spirits. “How am I supposed to sell fashion when even people who go to shows don’t wear fashion?” she asked ruefully and rhetorically. She was referring to the way the continuing casualization of style has been taking a toll on designer fashion at large. She was right. Today, one can see fashion insiders sporting Adidas track pants or a Nike jacket worn by a so-called “fashion person,” as likely as say a Rick Owens leather or a Celine bag. Last season, Instagram feeds of street style photographers were flooded with images of fashion people in Thrasher magazine t-shirts. This time the trend seemed to pivot in a new direction, as time after time I spotted attendees in various band t-shirts – Hole, Pink Floyd, Nirvana, and so on.
