Make "denim on denim" a mantra this season with Pierre Hardy's Obi slingback pumps, mixing American nonchalance with Parisian savoir-faire. Crafted in Italy from rich indigo denim, the pointed-toe style features a low-cut vamp accentuated by the origami-style bow detail. At the back, an elasticated slingback strap and textured block heel complete the look.
