After the Kamakura period, as the curtailing mo is described as 'Not a hanging kogoshi' seen in historical materials from the middle of the Muromachi period (Kumoino Minori (The Rites)), kogoshi of mo became clothes that hang over the shoulders and are not tied at the waist (koshi or goshi), however, the name kogoshi continued unchanged.
鎌倉時代以降、室町中期の記録で裳を略すことを「小腰をかけず」と表記する（雲居の御法）ことで表されるように裳の小腰が「腰で結ぶ」ものから「肩に掛ける」ものになっても、依然「小腰」の呼称は失われなかった。
