It is named after Lord Raglan, the 1st Baron Raglan,[2] who is said to have worn a coat with this style of sleeve after the loss of his arm in the Battle of Waterloo.[2] The Raglan sleeve was invented by coat producer Aquascutum for Lord Raglan to allow him room to use his sword in battle. It gave greater movement to the wearer, instead of the usual sleeve head which was prefixed.
