As a Westerner, feel free to wear anything, as long it is not very revealing like extremely tight jeans, low-cut blouses. It is extremely important for women to keep their legs covered as much as possible by wearing long skirts or pants. Shorts are never acceptable, except at beach resorts. Be sure to wear a hat. It is essential protection against the sun. Men should not, however, wear turbans. Cotton outfits, hats, sun glasses and sun screen lotion should be carried while on your tour to North East India.
