Last season, designers were all about exposing the body with sheer layers; the season before that, they couldn’t get over the corset trend. For spring 2023, they’ve gone one step further, with a trend all about how clothes are pieced together and — notably — how easily they can come apart. At many shows, this was translated in recognizable ways: at Erdem, dresses were either left half unpainted or practically cut to slivers, their frayed edges clearly visible; at Eftychia, lines of delicate buttons were left undone, creeping up the sides of models’ skirts or across the front of dresses, carelessly left open. Susan Fang, Rejina Pyo and JW Anderson each offered loose, spiderwebbed or fisherman knits — one tug and they’ll unravel. Simone Rocha helped puffs of tulle explode from cut-outs, purposefully attached chunky, exposed zippers just begging to be undone and let buckled, utilitarian straps dangle temptingly.
