Jung Wook-jun

Jung Wook-jun is a South Korean fashion designer, founder of JUUN.J and the central author of one of Korea’s most internationally visible designer houses. Trained at ESMOD Seoul, he worked in the Korean and international menswear market before launching Lone Costume in Seoul in 1999, a label that built a domestic following around precise tailoring, deconstruction and a sharper vocabulary of masculine dress.

In 2007 Jung reworked that practice under the JUUN.J name and introduced it to Paris Men’s Fashion Week. The move turned a Seoul cult label into a global house with a clearer international identity, based on what he has described as the “Diversion of Classic”. Trench coats, MA-1 jackets, suits, uniforms and parkas became the recurring material for a practice that studies classic dress by altering its volume, construction and social code.

Jung’s position widened after Cheil Industries acquired JUUN.J in 2011 and the brand later came under Samsung C&T Fashion Group. He remained creative director, became the first South Korean designer invited as guest designer to Pitti Uomo in 2016, and was promoted to an executive role within Samsung C&T Fashion Group in late 2023. His career links independent Seoul menswear, Paris institutional visibility and the corporate scaling of Korean fashion without separating those chapters from the clothes themselves.

Jung Wook-jun’s design ethos is built on revision. He begins with familiar garments — the trench, the tuxedo, the bomber, the parka, denim, military clothing — and changes the logic of their authority through scale, layering and reconstruction. His silhouettes often look oversized at first glance, but the effect depends on controlled engineering: heavy shoulders, long sleeves, wide bodies, cinched waists, hard panels, deep pockets and fabric weight doing visible structural work.

The term “street tailoring” is useful because it keeps both sides of the practice in view. Jung does not abandon tailoring for streetwear, and he does not polish streetwear until its edge disappears. He brings denim, workwear, sportswear and technical outerwear into a tailored system, then lets friction remain. Black, leather, wool, cotton, nylon and denim recur as a pragmatic palette for experiments in volume and surface.

His genderless approach follows the same discipline. The “-less” vocabulary attached to JUUN.J — genderless, boundary-less, formless — is not a move into generic unisex dressing. It keeps the same architectural codes across menswear and womenswear, allowing skirts, dresses, suiting, outerwear and military forms to share one design grammar. The result is severe without being static: classic dress is kept in motion, tested season after season against youth, function and the changing body.
