Musannaf Ibn Abi Shayba 16:670

Abu Bakr narrated to us, he said: Hisham narrated to us, from Mughira, from al-Sha'bi, that the daughters of Husayn ibn Ali used to wear the *qamis* (shirt/tunic). When they reached puberty and were married, they would wear the *duru'* (long, loose-fitting garments/chemises).
