This classic men's long-sleeve button-down shirt features a sharp vertical stripe pattern in navy blue, red, and white—evoking a timeless nautical or preppy aesthetic. Crafted from smooth, likely cotton or cotton-blend fabric, it offers a crisp drape with subtle sheen, ideal for structured yet comfortable wear. The shirt includes a standard point collar with button-down tabs, a full front placket with clean white buttons, and neatly finished barrel cuffs with matching striped trim. Tailored fit through the torso and sleeves ensures modern silhouette without excess bulk. Interior yoke lining adds durability and a refined finish. Perfect for smart-casual settings: pair with chinos for office-appropriate attire, or roll sleeves and team with jeans for weekend versatility. Breathable fabric makes it suitable for spring and summer layering or standalone wear in mild climates. No visible branding or logos on exterior—suggesting a generic or private-label design rather than a designer house.
