I have learnt a lot from Calvin Klein. From the moment I landed in New York thirty year ago, it was Klein who made me falling in love with American fashion. From him I have learnt about the power of simplicity to transform lives and aesthetic sensibilities, about the magic of industrial materials, about the beauty of colorless design, that obsession for detail is the only way to really achieve perfection, and about how a passion for the pristine can develop into a life-long lust. Walking into the Calvin Klein store on Madison Avenue which was designed by British Minimalist John Pawson is still my most favorite shopping experience, and his presence is my closet my closet surpasses any other designer. This week, Klein spoke at Harvard Graduate School of Design about the architecture and fashion and about his love for space, for Donald Judd, for Jean Prouve, Serge Mouille, Pierre Jeanneret, Le Corbusier, and for ancient art. In this talk, which is illustrated with amazing images, Klein illuminates on the philosophy of advertising during his career as a fashion designer and reveals the homes he has made for himself, informed by his passion for design, space, and light. To me, Calvin Klein is a hero, the Steve Jobs of the fashion world.
