Mahatma Gandhi
He has not been just a half clothed man all his life. Only has a old man in a hot and humid climate, he choose to wear what all old common men wore for that climate at that time(80 years back).
Moreover one of the aspect of Satyagraha (non-violent struggle) is to intimidate and embrass one who unjustly subjucates, by being present with utmost simplicity and conveying in strongest manner the injustice that is brought to one self.
