Derelicte is really happening.

Twelve years after the Ben Stiller-as-supermodel classic “Zoolander” introduced the concept of a garbage-inspired fashion collection, real-life designers appear to be reprising trash as a trend. For anyone who needs a reminder, Mugatu, the bad-guy designer in the film, says: “Let me show you Derelicte. It is a fashion, a way of life inspired by the very homeless, the vagrants, the crack whores that make this wonderful city so unique.”

Well, let me show you the real Derelicte. On the spring runway at Lanvin, there were shiny purses that looked very much like Hefty bags. At J. W. Anderson and Giambattista Valli, there were tunics and dresses that looked as if they were made from cardboard boxes. And at his New York show, Marc Jacobs created a set strewn with detritus, calling to mind a post-apocalyptic wasteland.
