The fashions of Tamás Király were not made for the marketplace. Hungary’s star avant-garde designer—who ascended in the 1980s and was murdered in 2013—was an artist whose medium was fashion. He was not interested in posterity or a brand, only in the moment, and no one pretended his pieces were truly wearable. They were Constructivist sculpture, glittering fantasias, comments on luxury. —L.J.
