his is a men's long-sleeve, slim-fit denim shirt in a deep, vibrant indigo blue with a subtle marled or heathered texture. It features a classic spread collar, a smooth button-down front with matching blue buttons, and a small, tonal (likely black or dark blue) embroidered logo on the left chest. The shirt appears to be made from a soft, lightweight denim or chambray fabric, offering a polished yet casual look. It's styled here as a clean, untucked button-down for a modern, smart-casual aesthetic.
