The Henley shirt is a collarless pullover with a round neckline and a short row of buttons on the chest, making it look like a more refined, structured version of a standard T-shirt. Originally worn by 19th-century English rowers for athletic comfort, it is made from lightweight materials like cotton or textured knit fabrics. It can be found in both short and long sleeves, and because it bridges the gap between casual and polished style, it is highly versatile—perfect to wear on its own for a clean look or layered under a jacket.
