What is a raglan?

A raglan is a type of sleeve that extends in one piece fully to the collar, leaving a diagonal seam from underarm to collarbone. It is typically used in clothing as a design element on a shirt, sweater, or sweatshirt. The raglan sleeve was named after Lord Raglan, the First Baron Raglan, who lost his arm during the Battle of Waterloo. It is a more relaxed and comfortable type of sleeve that allows for greater movement and flexibility, and is often used in athletic wear. The raglan style has also become a popular design element in fashion, with designers experimenting with different colors, prints, and materials to create unique and fashionable garments.
