What is a raglan sleeve?

A raglan sleeve is a type of sleeve that extends in one piece from the collar to the underarm. This style of sleeve is characterized by diagonal seams that extend from the neckline to the underarm, rather than the traditional vertical seam that runs from the shoulder to the underarm.

Raglan sleeves are considered to be more comfortable and allow for a greater range of motion compared to traditional set-in sleeves. They are commonly used in activewear and sportswear, as they provide a more relaxed and flexible fit.

Raglan sleeves were popularized by Lord Raglan, a British officer who lost his arm in the Battle of Waterloo and required a more functional and comfortable sleeve design. The raglan sleeve style has since become a classic and timeless design element in fashion and apparel.
