However, when there are expressions such as 'noshi sokutai' in kuge diaries, they may mean 'there is someone in noshi or someone in sokutai' when you closely read them, and it is known there were shozoku called 'noshi sokutai' (composed of noshi no ho [round-necked robe]), ue no hakama (outer trousers), sekitai, shitagasane (long inner robe), etc. in the mid Heian period, so the theories above require rigorous verification.
ただし、公家の日記に「直衣束帯」などの表記がある場合も、丁寧に解釈すると「直衣を着た者や束帯を着た者がいる」の意味である場合もあり、平安中期には「直衣束帯」という装束（直衣の袍・表袴・石帯・下襲等より成る）があったことも知られるなど、上記の説については厳密な検証が必要と思われる。
