This article originally appeared in ‘Hypebeast Magazine Issue 33: The Systems Issue.’ The first time South Korean designer Jiyong Kim encountered sun-bleaching, he was walking through Seoul’s fabric markets on a hunt for inspiration. At the time, he collected vintage denim and military pieces, but a chance encounter with a trench coat changed his life’s trajectory.

The jacket had been displayed out in the sun for months and developed a faded pattern, unlike anything he had seen before. That lightbulb moment eventually led to his eponymous brand’s signature aesthetic. Where others saw defects, Kim saw the beauty of imperfection.

By harnessing the power of sunlight and the elements, he realized he could use their effects — discoloration, roughened textures, one-of-a-kind patterns — to treat his clothing designs, yielding startling results. While studying at Bunka Fashion College and Central Saint Martins, Kim worked at LEMAIRE , Louis Vuitton (under the late Virgil Abloh ), and Maison MIHARA YASUHIRO , simultaneously honing his own design practice. He officially launched his own brand, stylized as JiyongKim , in 2021 after the Tokyo-based shop GR8 bought almost the entirety of his thesis collection.

Eventually, shops like Dover Street Market , MR PORTER , and 10 Corso Como began carrying his weather-warped wares. As Kim’s label has grown, he’s refined his experimental treatment practice, getting it “down to a science.” After extensive lab testing, he knows.
