A raglan sleeve does not refer to a length of sleeve but rather a style. This distinctive look is also referred to as a baseball T-shirt because the style is used in most baseball uniforms. In this style, the sleeve is attached to the shirt on a diagonal instead of a straight up-and-down seam. Often, this style uses different colors of fabric for the sleeve and the bodice to emphasize the lines. This look is most often associated with a sporty style for both men and women.
