This classic long-sleeve button-down shirt features a warm-toned plaid pattern in rich brown, beige, and off-white hues, crafted with a textured herringbone weave for added depth. Made from 100% cotton using a brushed 'máo máo gōng yì' (fuzzy/mill-finished) process—indicated by the Chinese text '磨毛工艺'—it offers softness, breathability, and enhanced warmth, ideal for transitional seasons. The shirt includes a standard pointed collar, chest pocket with buttoned flap, and functional sleeve cuffs with two-button closure. Its relaxed yet tailored fit makes it versatile for daily wear, layering under jackets or wearing solo. Perfect for casual outings, office-casual settings, or weekend errands. The fabric’s slight nap provides comfort against skin while maintaining structure. Model number 3209# suggests a specific cut or seasonal variant. No visible brand logo is present on the collar tag (only size '41' and indistinct marking), confirming it as an unbranded or generic design product.
