The stand collar jacket arrives as a study in restraint and refinement: navy wool knit that catches light without gloss, woven with an all over geometric pattern inspired by kumiki, the interlocking woodwork technique passed down through centuries of Japanese craft. The pattern emerges from a double jacquard weave, fine wool threads forming the base while bright polyester yarn creates the delicate lattice that gives the piece its subtle luminosity.

Construction speaks to precision. The body follows a straight silhouette with considered volume, neither spare nor voluminous, while the stand collar and matching fly button front borrow from jacket dressing without formality. The effect is supple and effortless; this is outerwear that layers without weight, shaped to move with the body rather than against it.
What distinguishes this piece is the interplay of its materials. Wool contributes its inherent warmth and gentle texture, while the polyester threads introduce a restrained shimmer that surfaces only when light catches the jacquard. The result feels both contemporary and rooted in tradition, a jacket equally at ease over a simple cotton shirt or a fine knit base layer. Available in sizes S through XL, it finds its place in the wardrobe as one of those essential layers that bridges seasons and silhouettes, made by Blue Blue Japan in collaboration with Seilin.
