The 81% polyester, 10% wool, 9% polycarbonate blend produces a fabric with a wavy, raised surface that cannot be flattened without breaking the construction. Each wave is built into the weave itself -- not a finish applied on top, but the fabric's actual three-dimensional architecture. The result is a surface that has depth and shadow even when the jacket is laid flat, and that generates new visual geometry as it moves with the wearer. The central back seam bisects this textured field with a clean vertical line, the single resolved element in a surface designed to be deliberately irregular.

The silhouette is cropped at the waist with wide sleeves that extend the horizontal volume of the piece -- the proportion is deliberately wide-shouldered and short, a geometry that creates presence at the top of the body without length. Patch pockets and a large button closure add utility without competing with the surface. The unlined construction allows the 3D weave to breathe and move without being compressed against a lining, keeping the wavy topography fully expressed rather than partially flattened. Nostra Santissima uses this kind of fabric engineering to produce a piece that earns its place in a wardrobe built on materiality -- not through dye or treatment, but through the textile's own structural logic.
