The "69" sub-line applies Sellam's industrial grammar to fabrics outside his leather archive. Here the vocabulary is linen: a lightweight jersey knit, cold-dyed after the tee is sewn so the pigment settles at seam channels more densely than on flat panels. On white, the effect is subtle - a faint tonal shift at the shoulder overlock and the neckline binding, the kind of surface detail that reads only in direct light. A narrow leather insert runs the length of the back. The Steel Staple 69, a single gunmetal agrafe pressed through the fabric, marks the piece at the collar seam. Handmade Paris atelier, same workshop as the leather pieces, different material priority.
