Tailoring hits the throttle.
JUUN.J and Alpinestars RSRV collide at full speed, bringing Korean architectural tailoring into the raw, protective language of the racetrack.
First unveiled on the Paris runway for JUUN.J FW26, the collaboration turns racing equipment into something less functional, more feral. Leather. Padding. Reinforced volumes. Rider jackets blown out of proportion. Familiar silhouettes pushed until they start looking almost mechanical. Six collaborative looks appeared on the runway, marking the first chapter of a partnership built around a shared obsession with reconstruction.
JUUN.J calls its approach “Diversion of Classic”: take the codes you know, distort them, rebuild them, make them strange again. RSRV works from the opposite end of the spectrum; taking the materials, construction and technical DNA of Alpinestars’ racing heritage and reverse-engineering them through a form-first lens.
The result sits somewhere between pit lane and atelier.



There is no costume-racing nostalgia here. No easy logo flex. Instead, protection becomes proportion, performance becomes silhouette, and the motorcycle jacket mutates into something closer to sculpture.
The old rules are still visible.
They’ve just been pushed past the limit.
