The form of "Jeogori" has changed over time. While men's "jeogori" remained relatively unchanged, women's "jeogori" dramatically shortened during the Joseon dynasty, reaching its shortest length at the late 19th century. However, due to reformation efforts and practical reasons, modern "jeogori" for women is longer than its earlier counterpart. Nonetheless the length is still above the waistline. Traditionally, "goreum" were short and narrow, however modern "goreum" are rather long and wide. There are several types of "jeogori" varying in fabric, sewing technique, and shape.
