Officially, men wear black nagagi (full-length garments) with five family crests and striped hakama, and women wear black or color tomesode (formal dress patterned only below the waistline, as worn by a married woman) with family crests and machi hakama, following the code for traditional Japanese clothing; but there are no rules and often different clothing is worn.
正式には和服の慣例に準じ、男性は黒の5つ紋付の長着に縞袴、女性は紋付の黒または色留袖に襠袴だが、規定は無くそれ以外が着用されることも多い。
