There's something about a pair of great jeans can make your cold-weather wear entirely effortless. So, as we head toward Fall, we're admittedly a little obsessed with our denim pieces. Along those lines, certain icons come to mind when we think easy denim, women who epitomize the perfect fit with silhouettes that flatter and styles that feel entirely their own.
