Widely recognized as among the most important and influential designers of the past forty years, Rei Kawakubo of Comme des Garçons has defined and transformed the visual language of our time. Since her Paris debut in 1981, she has blurred the divide between art and fashion and transformed customary notions of the body, beauty and identity. This lavishly illustrated publication weaves an illuminating narrative around Kawakubo's revolutionary experiments in interstitiality—the space between boundaries. Brilliant new photographs of more than 120 examples of Kawakubo's womenswear for Comme des Garçons, accompanied by Kawakubo's commentary on her designs and creative process, reveal her conceptual and challenging aesthetic as never before. A chronology of Kawakubo's career provides additional context, and an insightful conversation with the author offers a fascinating glimpse into the mind of this fashion visionary.
