Pack comfortable clothes that allow you to stretch and contract your body. We call it yoga clothes. You may want to cover your body when working on different poses, be careful while choosing the clothes. If you want to swim in the Ganga, pack something that would cover you well and you will like to soak. We don’t recommend our students to jump to the river with swimming costume, for Indians and Hindus worldwide, Ganga is the holy river who they worship and pray to. They bathe in the holy river with a belief that they will be liberated from the worldly pain and pleasure. Also, you will certainly want to avoid people staring at your body. Carry some modest clothes for pilgrimage tours and to roam around in the city. Try to cover your body while roaming around because this is India, people here have a culture of covering themselves. Comfortable shoes have no option. You can also bring light flip-flops or choose to buy here in cheap rate as low as INR 200 (may be less than that).
