I disagree with you two though. I don't mind this sculptural period in Rei Kawakubo's legacy for the simple fact that she is one of the few designers immune to the vicissitudes of fashion (and thank God for it). The fashion industry has always been subject to the governing forces of time - contemporaneity, nostalgia, futurism, history, vogue, cycles, seasons - and the typical or even the great designers make clothes in dialogue with these forces. If you want a designer that tasks himself or herself with navigating these spheres of fashion, then you can look to every other collection outside of Comme des Garçons. But Rei Kawakubo has never chosen to navigate these spheres, in a sense she is almost beyond the vicissitudes of fashion, and to expect her to be in dialogue with the idea of modern dressing is to go on a fool's errand. I would argue she exists outside of fashion, or perhaps ironically represents its purest, undistilled form, and in this way she is similar to that other lone genius of fashion history: Cristobal Balenciaga.
Besides, if you want to see her work within the perimeters of fashion, there are her men's collections to peruse. Also, it's something ingrained in fashion, but those who appreciate it can get lost in fashion's manufactured idea of time. Rei Kawakubo has only been in sculptural mode for five seasons so far. Five seasons is a very small drop in the bucket. Her legacy stretches decades, and I'm looking forward to where she goes after this period. As of now, I'm enjoying how she is able to make something beautiful out of something so impractical to wear, how these resemble clothing but are not quite clothing, and I choose to remain patient because Rei Kawakubo does not work under the same conditions as her contemporaries. No themes, no explorations, no references, no allusions, no proposals, no trends, no distinctions between the seasons, no attempts to be modern or nostalgic or futuristic, no need to conform. Just ideas about clothing.
