If it's managed to stick around since the 1940's you know it's got to be good. Meet the slingback heel - a style that has uncannily managed to reinvent itself for decades. They're the perfect way to add a touch of classic charm to your outfit. If your taste is preppy, go all out and pair yours with structured bags, and polished outfits. If you were looking to put a relaxed, contemporary spin on your look though, then opt instead for outfits featuring looser, distressed denim, t-shirts and fun micro bags.
