This blazer skips the break-in period because it was already broken in before you touched it. AITO's garment-washing process takes constructed cotton twill and tumbles it with stone and enzyme treatments until the fabric loses its stiffness. What you feel in your hand is not new cotton - it is cotton that has already lived, softened, and settled into the body it will hold. The surface is matte charcoal with tonal variations where pigment concentrates in folds. Heavy enough to structure your shoulders without padding, light enough to wear through three seasons.
The fraying is technique, not accident. Every edge - collar, placket, cuffs, hem, pocket openings - is cut raw and left to fray into a 0.5-1cm halo of black threads. The horizontal elbow piecing seam runs across both sleeves, a subtle construction detail that breaks up the silhouette. Three-panel back creates dimension. Four-button closure with patch pockets. Boxy relaxed fit with unstructured shoulders that drape rather than stand. The cotton is quiet when you move - no rustle, no sound, just weight settling across your back.
Wash it cold. The frayed edges will soften further, curl slightly, become more themselves. The pigment will fade where friction is highest - cuffs, elbows, collar. This is how heavy cotton ages when it is allowed to. AITO does not hide the process. The raw edges tell you exactly what this garment is built to do.
