A garment featuring sleeves that extend in one piece fully to the collar, with a diagonal seam running from the underarm to the collarbone, is a distinctive style of shirt. This design contrasts with set-in sleeves, where the sleeve is attached to the body of the shirt at the shoulder. A common example is a baseball shirt, often with sleeves of a different color than the body.
This construction offers an increased range of motion and a comfortable fit, making it a popular choice for athletic wear and casual apparel. Historically, this sleeve design is attributed to Lord Raglan, who reportedly wore a jacket with such sleeves following the loss of his arm in battle. The design allowed for easier movement and a more comfortable fit with his disability. It has endured as a functional and stylish option, blending practicality with a distinctive aesthetic.
