Revivalism isn't easy. Customs and traditions change frequently. All evidence suggests that the tradition required pilgrims to take off their cloths inside the cave at Amarnath. Something akin to what still Naga Sadhus do at Kumbh Melas across India. Evidence suggests this is not done anymore at Amarnath, none of the recent photographs of the place suggest this.

Recently, in a documentary (uploaded by British Pathé ) about Amarnath from 1960 titled 'Himalayan Pilgrimage', I came across the same pile of cloths.
