The Raglan Sleeve

A Raglan sleeve is a type of garment sleeve that extends diagonally from the collar to the underarm, rather than attaching at the shoulder seam. This design creates a seamless, smooth connection between the sleeve and the body of the shirt, often giving a sporty or casual look. Raglan sleeves are popular in athletic wear and casual clothing because they allow greater freedom of movement and reduce shoulder seams, providing comfort and a clean, distinctive appearance. The style is named after Lord Raglan, a British army officer, though the design was used in sportswear long before his association.
