The great pantheon of fashion designers produces only a handful of creators who are masters of their métier. Rei Kawakubo of Comme des Garçons is one of them. Widely recognized among her contemporaries as the most important and influential designer of the past forty years, she has, since her Paris debut in 1981, defined and transformed the aesthetics of our time. This lavishly illustrated publication examines Kawakubo’s fascination with interstitiality, or the space between boundaries. Existing within and between dualities—whether self/other, object/subject, art/fashion—Kawakubo’s work challenges the rigid divisions that have come to define received notions of identity and fashionability, inviting us to rethink fashion as a site of constant creation, re-creation, and, ultimately, hybridity. Featuring brilliant new photography, and thought-provoking texts by Andrew Bolton, this book expresses the conceptual and challenging aesthetic of this visionary designer. An insightful interview and illustrated chronology of Kawakubo’s career provide additional context.
