Try to dress modestly while travelling in India. It is recommended both for men and women to choose loose clothes covering shoulders and knees. It is generally known that India has very conservative dress standards, especially in rural areas. Here you can hardly find a man wearing shorts or a woman wearing skirt above the ankles. In urban places like Mumbai and Delhi western dress style, including jeans on woman, is prevailing. Liberal views on dress are typical for Goa too: it is all right here to wear anything you want for night party, but still, in day time it will be better to dress more suitable for Asian mentality. Anyway, if you’d like to show respect to Indian culture and to feel yourself comfortable, you might find appropriate to dress yourself “locally”. Kurtas (loose men shirts) and cotton pants would be good option for men, and salwar kameez (tunic and loose trousers) for women.
If you need transportation in India, contact your tour operator or your hotel stuff to hire a taxi or a car with private driver. Driving on your own could be uncomfortable due to intense traffic and typical Indian street chaos. Travelling in public transport could be also challenging in India: you will be really fortunate if you could get a seat there. Optionally, if you need to get on the market or on the beach you may use notorious Indian rickshaw.
