The term 'Type of Sleeve' can refer to two different types of sleeves: RAGLAN (6 letters) and Gigot (5 letters). A RAGLAN sleeve is a type of sleeve that extends in one piece to the collar, creating a diagonal seam from the underarm to the neckline. This type of sleeve is often used in sportswear and casual clothing. A Gigot sleeve is a type of sleeve that is full and gathered at the top and bottom, creating a bell shape. This type of sleeve is often used in formal or evening wear.
