We love the idea of wearing leather leggings in the Fall, not only because they're a great substitute to jeans, but they inject instant cool-girl appeal to just about any ensemble. That's why these Elizabeth and James Diedrick leather leggings ($895), are on the top of our Fall investment purchase list. The dark reddish brown hue is a standout color, yet earthy enough to pair with almost every hue. Secondly, we love the cool silver buttons and luxe textural feel; such attention to detail make this pair shine in the leather pants department. The price tag is no joke, but it's an investment worth making, because they're so versatile. To prove it to you, we styled them five different ways, starting off with this cute office-appropriate look and working to more festive, cocktail-ready ensembles.
