Barneys Co-Op (CLOSED)

This hip younger sibling to the high-society namesake is the place to go for designer denim from names such as Habitual, Imitation of Christ, Earnest Sewn and Superfine. The his-and-her store’s vibe is less intimidating than Barneys proper, but the prices are just as stratospheric—so don’t be surprised if you do more looking and lusting than buying.
