Denim skirts...you match everything. Polos, sweaters, turtlenecks...name something that doesn't work with dark denim (and isn't work/super dressy). You think of anything? That's what I thought. I love this knee length dark dark denim skirt from true religion. Nice enough you could rock it in heels and a nice shirt, but also able to be worn with flip flops and a casual polo or cami.
