Although there were some differences between the sokutai worn by civil officers and that worn by military officers, military officers with a rank of Sanmi (Third Rank) or higher and civil officers both wore a hoeki no ho (robe with a round collar, stitched sides, and a ran that was worn by the emperor and high-ranking officials) and a suiei (a kind of "tail" that was attached to the back of formal headwear) attached to their kan (formal headwear).
なお、束帯には文官・武官による区別があり、文官と三位以上の武官は、縫腋袍を用い、冠は垂纓とした。
