Dutch sensation Iris van Herpen knows how to make an impact. Her sculptural creations and intricate workmanship are impressive, but often to the point of extreme. With a soundtrack of sinister pulsating techno music, her models hit the runway encaged in short dresses made of metallic and rhodoïd strips that swirled or spiked around their bodies like computer-generated plants, while a more organic dress looked like the model was wrapped in intricate tree roots. And one girl had to cautiously negotiate the runway wearing van Herpen’s latest designs for United Nude — multiheeled shoes. That said, there were two “wearable” looks, but they lacked the inventiveness of the rest of the collection.
