Well, now I know where Lady Gaga gets her post-McQueen heels. For me, art-not-wearable. But stunning. Part of Iris van Herpen's X United Nude Crystallization Collection. Individually crafted with Italian leather, woven chains and leather laces envelop foot, wearer, and even the space between sole and heel. Limited editions (may be) available at United Nude for $995. Iris van Herpen was born in the Netherlands and interned for McQueen before launching her own fashion label in '07.
