The unspoken political rule that political leaders should avoid putting anything on their heads apparently has no place in India.
Indian Prime Minister Narendra Modi showed up at the parade wearing a safa, a traditional celebratory headdress that some Indian men wear for festivals and special occasions.
Modi's had a large, red pleated circular plume and an orange scarf running down his back.
Obama stepped out of his limousine and into the rain bare-headed. The president once said that “you don't put stuff on your head if you're president.“ But he broke his rule last year by posing in a tiara with members of a Girl Scout troop.
