It has been recalled through a series of memoirs by Ayatollah Khamenei, the leader of the Islamic Revolution that imam used to attach great importance to appearances.
When many seminary students and scholars were not too much punctual about their appearances, Imam regularly looks into a mirror which he had fixed by the wall, Ayatollah Khamenei recalled.
Imam was well-organized and always showed discipline in his all works.
