Futuristic structuralism — fifteen years of re-tailored tailoring

KUMANN YOO HYE JIN is a high-end avant-garde womenswear house with roughly fifteen years on the Seoul Fashion Week schedule, known for architectural and structural design and for its part in the Retro Futurism and Brutalist Architecture currents. At its heart is a futuristic structuralism rooted in Hyejin Yoo's own modélisme, and a stated method the house calls "Re-tailored Tailoring".
