How to Dress in India

When you're traveling, you have to keep in mind that other cultures have another dress code. To be clear, here is a summary.

Steps

Keep a scarf or a long cloth with you to cover area around neck and also face if required in emergency.
Don't go bathing on beaches naked or topless. Indian people also find a bikini disgraceful. Indian women mostly bathe while wearing a t-shirt and tights. If you don't want to wear a t-shirts and tights, you better look for a bathing suit or you simply don't go bathing.
For men, dress code is less strict. They can wear short trousers, but Indian people find it a little bit ridiculous for adults.
