From this time, the basic structure of hanbok, namely the "jeogori" jacket, "baji" pants, and the long, "chima" skirt, were already established. Short, tight trousers and tight, waist-length jackets, "twii" (a sash-like belt) were worn by both men and women during the early years of the Three Kingdoms of Korea period. Women also wore "baji" under their "chima" The basic structure and these basic design features of hanbok remain relatively unchanged to this day, except for the length and the ways the "jeogori" opening was folded as over the years, there were changes. Originally the "jeogori" opening was closed at the central front of the clothing, similar to a kaftan; the fold opening later changed to the left before eventually closing to the right side. Since the sixth century AD, the closing of the "jeogori" at the right became a standard practice. The length of the female "jeogori" also varied throughout time. For example, women's "jeogori" which are seen in Goguryeo paintings which date to the late fifth century AD are depicted shorter in length than the man's "jeogori".
