Just as the skinny jean paved the way for the popularity of the boyfriend silhouette, the leather legging has led to the slouchy leather trouser. Think of it as the intellectual cousin to the the legging’s edgy rocker. At Peter Som, the designer showed multiple iterations of the pants in black, dark green, and oxblood. Doo.Ri’s take paired cuffed, slouchy, black trousers with a simple navy turtleneck in her signature jersey. And over at Organic by John Patrick, a crisp, white shirt layered under two coats kept the look polished but relaxed. So next fall you can avoid that awkward shimmy you need to do to squeeze into leggings, and just zip and go.
