What Is A Raglan Sleeve?
A raglan sleeve is a type of sleeve that extends in one piece fully to the collar, leaving a diagonal seam from underarm to neckline. It is named after Lord Raglan, the 1st Baron Raglan, who is said to have worn a coat with this style of sleeve after the loss of his arm in the Battle of Waterloo.
